Online e-commerce looks like a huge opportunity to make money.
To what end?
Is that something you want to do and be doing? Said another way, do you want to subject yourself to that?
Is it a reward on its own? Or are you doing it for money?
Do you already have a way to make money, with some security, and with the idea of a way out if necessary?
Is it a fun game to play?
Why? You need immeasurable energy to keep it going for 5 years. 10 years for something big to happen.
