Running a small business and building wealth through compounding. I talk about startups, finance, investing, travel.

[Andrew Nguyen @WorkLifePlus]

My first business was a success, defying the odds when 90% of first-time founders fail.

Yet, I was clueless.

If I were to embark on this journey again, here’s what I would do.

But first, let me share a bit about my background.

Over a decade ago, I held a middle management position at a large multinational consultancy, enjoying a six-figure salary and all the accompanying perks. My office was nestled in a towering glass skyscraper in the heart of the business district.

I dedicated myself wholeheartedly to my employer, giving it my all and earning respect as a high performer.

However, my world shifted when I learned I was passed over for a promotion in favour of someone, albeit deserving, who wasn't superior to me in capabilities.

A month later, I marched into my boss’s office and tendered my resignation.

While my departure didn’t surprise anyone given my high performance and extensive professional network, my decision to start my own business left everyone stunned, assuming I would jump ship to another firm.

Leveraging my consulting background, I ventured into the consulting business. As demand for my services grew, I expanded my client portfolio and eventually stabilized my consulting income. With a solid foundation in place, I gradually explored riskier ventures.

So, if I were to start anew, here’s my plan:
1. Begin with a service-based business like consulting or coaching,
2. Stabilize and optimize it,
3. Diversify into product-based businesses,
4. And then explore other, riskier ventures.

What's your entrepreneurial journey? Share it with me in the replies below.
