If you look up all these billionaires you celebrate today…

You'll notice something common among them…

They solve a need.

Bill Gates(Microsoft), Elon Musk (Tesla), Mark Zuckerberg (Facebook) , Larry PAGE (Google) etc.
They all solve a need and that is why they are billionaires today…

If you want to become rich, solve a need. It's simple, people pay you for the need you solve.

If you're selling food, you're solving a hunger problem. People will pay you to solve that problem by buying what you're selling…

If you notice a particular need and build a product that solves that need, people will beg you to take their money and get the solution to their problems…

This also applies to services, not just products. Take for instance, copywriting (using words to sell)...

Business owners will pay you huge sums of money as a copywriter ( if you're good at it) because you're helping them make money through sales…

You've solved a need and they're happy to pay you for it!

That's how it works. Solve a need and people will pay you for it.
