I wouldn't term your state as lost, you are just 23 and graduated from a top university. You said you always wanted to start a startup, is it only to be a tech startup? you have experience in chemistry why not try something you're good at? If at the core you really wanted to make a difference at large scale it not necessarily be your own startup but you can also help folks who are trying to achieve it.

I think at the core of your approach for starting a startup is to make money. Apologize if that's not the case but from one of your comments,

> It seemed like local startups are getting funded with half baked ideas or clones and I thought that I could do just as well as them so I was pretty hesitant to find a job

This. maybe the reason, and anyway, I wish you the best.
