A job with constant money – A path others choose for you but with a promise of growth. In the end, making decent money.
Own startup or business – You decide the path, but no promise of money, risking a lot in life but doing what you want to do. In the end, may or may not make money.
How to decide?
Look at the impact you can create, look at the problem you can solve, and look at the number of lives you can touch.
Money is one important aspect but so are other factors, weigh your options wisely and decide.
