The 8-figure Portfolio

In 2020, I sat across from a sharp-looking businessman at a café in Lagos, Nigeria, listening as he casually dropped figures that made my head spin. With an 8-figure portfolio, he spoke with confidence, but there was a catch, a palpable regret in his voice as he recounted his mistakes. Sure, he had weathered economic downturns, he had thrived during booms, and built an empire from the ground up. But despite his success, he admitted that certain choices still haunted him. And as I sat there, I couldn’t help but wonder: how many investors, even at the top, feel like they’re still learning the hard way?

Reaching 8 figures is a goal many individuals dream of, but as anyone experienced in building wealth will tell you, hitting that mark does not necessarily mean you have mastered the game. There is a common misconception that once you are at 8 figures, it’s smooth sailing, but in reality, it is a continuous journey of trial, error, and learning from costly mistakes. The good thing today is, if you know where to look, you don’t have to repeat them to find success.

In truth, even those who have made it big are haunted by decisions they wish they could undo. And what if we could learn from their mistakes? What if we could sidestep their pitfalls altogether, skipping the struggle and heading straight to the winning formula?

Let’s talk about the 8 most costly mistakes that 8-figure investors in Africa and beyond regret, and how you can avoid them.

1. Chasing the Next Big Thing (Without Doing the Work)

It is easy to get swept up in the latest investment trend, especially when you hear the hype surrounding new markets or sectors. The allure of the next big investment opportunity, crypto, emerging tech, or the “next big startup.” But here’s the thing: chasing trends without understanding the fundamentals can be disastrous. An 8-figure friend I spoke to admitted that in 2021, he invested heavily in a shiny new app that was all the rage at the time. What he did not realize was that the app’s business model was weak, and within two years, the company collapsed. 

The lesson? Do the work. Dive deep into the market, the numbers, and the potential long-term viability before jumping on board. Focus on the fundamentals, look at long-term demand, sustainable growth, and economic stability. When you invest in these factors, you’re less likely to get caught in a bubble.

2. Neglecting the Power of Diversification

Don’t put all your eggs in one basket is a well-worn saying that holds true for a reason. Many businessmen have learnt the hard way that putting all their capital into a single sector can leave them vulnerable. It is like relying on one key player in a game to carry the team; one injury, one downturn, and it’s game over.

Even the most successful business moguls like Aliko Dangote didn’t build their empire by relying on one industry. They diversified into cement, construction, oil, agriculture, and more because diversification is your risk mitigation strategy. Carefully spread your wealth across different sectors; real estate, technology, agriculture, or even international markets and you will better withstand shocks. It is not about playing it safe, it is about playing smart.

3. Ignoring the Importance of a Solid Team

One of the biggest mistakes is thinking you can do it all alone. Over time, I’ve heard many say, “I thought I could do it all myself, but when the business scaled, I was overwhelmed.” They learned the hard way that a strong team is essential for growth, not just luxury.

Let’s learn from  successful entrepreneurs, like Jeff Bezos and Elon Musk, who didn’t build their empires by themselves. Bezos surrounded himself with a strong team to grow Amazon, while Musk relied on experts to bring Tesla and SpaceX to life.

The lone-wolf mentality is tempting, but a well-rounded team is essential for growth. Focus on building a team that complements your strengths. With the right people in your corner, you can scale faster and avoid costly mistakes.

4. Being Too Eager to Exit

In my consulting career, I’ve met countless business owners, and one common mistake I’ve seen is the rush for a quick exit. I once spoke with a client who sold his startup too early, underestimating its potential. By the time he realized its true value, the new owners had taken it public for four times what he sold it for.

Pro Tip: Timing your exit isn’t about rushing, rather it is about recognizing when your business is poised for its next leap. Learn to read market cycles and be patient. If the numbers say hold, hold. If they say sell, don’t wait too long.

5. Overlooking the Impact of Personal Bias

We all have biases, but in business, the market doesn’t care about your feelings. Personal preferences can cloud your judgment. For example, some Nigerian investors insisted on staying local, missing out on lucrative opportunities abroad. Successful investors, however, expanded globally and unlocked new opportunities.

Challenge your biases and separate personal feelings from business decisions. Let the numbers guide you, not sentiment. After all, the goal is to make money first, then fulfill personal desires.

6. Not Building in Flexibility for Change

Markets evolve, trends change, and businesses need to adapt or collapse. Investors who do not strategically  adjust to these changes strip themselves naked to risk. Think of a football team that sticks rigidly to its strategy when the opponent changes its game plan, chaotic isn’t it? That is because flexibility is one key to success.

So, build flexibility into your investment strategy. Be ready to pivot when market conditions evolve, and your portfolio will stay resilient.

7. Underestimating the Power of Networking

Your network is your net worth. If in 2025 you’re not networking, you’re definitely missing out. The most successful investors understand the importance of building relationships.

Even in politics, success often hinges on strong networks and collaborations, and this is applicable in businesses. Your network can connect you to better deals, lucrative partnerships, and opportunities you might never discover on your own.

It is not optional, it is essential. Attend industry events, collaborate with peers, and keep the lines of communication open. Sometimes, your next big opportunity is just one conversation away. In today’s world, relationships open doors that numbers alone never will.

8. Neglecting Your Own Well Being

The final mistake may seem unimportant, but trust me, it is the one thing that can bring everything crashing down. A successful fashion designer confided that he ignored his health and personal life in the pursuit of success and what was the result? Burnout, health issues, and fractured relationships.  

Your well-being matters. To be a successful business person, you have to be at your best because  one who takes time for self-care is better equipped to handle the pressures of building and maintaining wealth.
