When someone says its too late to consider entrepreneurship post 30 or post-marriage or post-parenthood, I emphatize (not agree) with them.
When someone comes to me and says I am venturing on my own because I am not married and I can afford doing it now, I smile at his immaturity.
I wanted to sky dive when I was in the US and my friend said, you should try this now because post marriage you should not. Guess what, I am married and waiting to go back to the US to do it (this time along with my wife).
Entrepreneurship is half risky than sky diving and more fulfilling.
Side Note: Remember, you are just married not dead.
