I do work 15 hours + a day already, and sleep 6 hours. It's just a matter of me dedicating the remaining time I have that I don't use for the startup, so that I'll have more time for the startup.

I take time off, and I'm really not stressed. In fact, I maintain a rigorous schedule of working out and running, and eating healthy.

I also don't drink or smoke even though most of my friends do(most of them were in College).

Thanks for the tips, but I'm really not impatient, and each step I take is carefully planned.
