You're not being impatient. But what you need to learn is how to parlay opportunities.

Use your current job to build a 6 month nest egg (calculate what you need to live on if you won't earn a penny for 6 whole months). Then parlay that 6 month safety net to start your own venture, or become part of another startup as a founder with more equity options.

And in the mean time, learn all you can from your current job. Not just about your work - but about how the company is creating its strategy, how its hiring people, how it manages folks, how it handles finances and gets external funding, how it gets clients - try to pick up a bit about everything.
