I failed at two startups before my current one, which is close to launch. After each failure I took a break, feeling weak and like failure just like you are. But time heals all wounds. Before too much time had passed (a couple years) the excitement (and finances) had returned, and I jumped back in the game. I feel much, much stronger for the experience of those 2 failed startups. I don't regret them one bit. Sooner or later you'll probably feel grateful and happy for the experience you had, failure or no. Why not start now?
I've always wondered -- how does one recover from the financial setback of the initial failure? In good times, this may be easier if one either has savings or can quickly find a job to fall back on. But in times where jobs may be more scarce, how does one get through this?
Also, do the subsequent funding rounds get easier or harder? Do subsequent startup funds lean more towards VC or angel sources, assuming that one cannot save as much for the next rounds for a self-bootstrap?
I completely understand that the emotional roller-coaster must be difficult to overcome after the first setback, with a similar toll for a spouse/partner and family. How do people also overcome the financial setbacks?
