1. Startups are tough and I am afraid.

2. I have a few financial responsibilities towards my family which I have to take care of.

You're 25. What a great age to be! To be young enough to take risks, fail, and get back up and begin again. In my experience, most of those who were/are successful in their endeavors, were at the brink of financial failure and dealing with both issues you mention, when the risks paid off quite literally overnight. Of course startups can be absolutely huge undertakings, but the risks and rewards involved are the reasons we go after them.

Don't miss out on a chance at your passion because you were too afraid or intimidated. Regret sucks. There are just as many lessons (or more) in failure as there are in success for the next project you take on. Regret has nothing to offer but regret. It's a complete waste.

Go after what makes you happy--no matter what and never ever stop. Anything less and you will remain unfulfilled as you mention in your opening statement. Go get it and good luck!
