1) The combined net incomes from both ventures is not enough to fully support my financially right now (not to mention I have partners for both companies so it's not like I can take all of the profit for myself anyway). I've got enough savings to support myself for about a year with zero income, so I've got a bit of a runway to see if things will work out and find a job if I need to, but it's still a large gamble.
2) My employer is already trying to hire another developer and has been trying to do so for a few months. Considering how hard of a time they're having finding one developer, I'm concerned that my leaving would put them in a very bad situation. I'm really good friends with everyone at the company and I'm worried that there might be some resentment towards me if I do leave. Then again, I'm not giving them 100% and that isn't fair to them anyway. If I don't quit it's possible that I might be fired down the road anyway.
Have any of you gone through this before? Anyone have any advice? Is there anything I'm probably not thinking about that might blindside me down the road?
Thanks!
