First at all what time do you have with your company?
Raise a company from the ground is hard, requires a lot of effort and patience. If you are alone you need some diffusion about your product, and make a product good enough to compite with others.
If you have a long time with the startup and you see that not going so well, and you try different things, think about it, why it's not raising? why it's not generating revenue?
If after all you consider you make all the posible, maybe it's nice to go for a full time job and maybe try later.
