Ask HN: job or no job?

I'm at possibly my last year in college. The last months I've been working on as a remote developer for a company in order to get enough runway for living this year without working for another company.

I'd like to finish college and start a business this year but the problem is the ideas I've doesn't motivate me enough to pursue them, so I don't have a specific idea in mind in order to start working on it right away.

1) Continue working for the company and try to come up with an interesting idea for a business. I won't have free time to experiment with new things but I'll have extra money to use, maybe, in an intelligent way.

2) Stop working and invest the time learning new things, talking with people, making small projects... Maybe this way I'll come up with an idea faster than (1). But I have to take into account the opportunity cost here.

3) Maybe I can get some freelance projects while doing (2) but taking care of not converting that to (1).

I'd like to know what you think about it, what option(surelly there are more) do you think is best, maybe you could help me realize something I'm not considering.
