Co founder of Startup Weekend, author and passionate about innovation and startups, I'd be happy to help you around my favorite subjects : pre-startup phase and scaling up.
My recipe
1. Do sport
2. When feeling low, don t do anything as you'll suck at it, instead go out and meet people or just treat yourself with whatever you love
3. Look for co-founders : I wrote this paper, hope it will help you too :)
