I agree, but working for the startup of someone else you might learn from an awesome team that will prepare you for one day having your own startup. This was the advice of D'Angelo, from Quora, at the last Startup School.

I think it all depends on how prepared you are. If you think you have already learned enough, then go for it.

So, good luck with your startup! :)

I guess it depends where you are in life and how valuable a potential learning experience with a good team might be for you.

My feeling is there is no greater motivator for learning than when the problems you face may have a direct bearing on your own financial well-being and the life or death of your own startup.
