Part of the reason you are lost is because you have no experience. You are trying to solve problems with startups, but the quality and profitability of the problems you can solve at 25 is not that high. Simply because you have not seen enough. The other part of the reason is that our (I am 28) generation has a lot of freedom and a lot of free time too, we are having troubles dealing with that, many just waste time/freedom on useless stuff (carrier, facebook, TV, etc.), others “waste” it thinking of how to obtain a better future (financial freedom, sounds a bell?). My advice is: go out, go have some fun; meanwhile get good at whatever job you are doing and I ensure you that in a couple of years you will have seen lots of profitable/interesting problems worth solving.
