Has anyone started multiple startups at the same time?

@sergey_voynov Well say no. The first rule would be to be committed to the problem because 1. You have the problem yourself and 2. Because you understand the problem really well (as in you will or Have started, but usually if the idea is really good you would've jumped right into learning everything you can). Then stay focused on releasing the Minimal experience possible for whatever it is and keep speaking to your community and keep iterating. If you have new ideas (which you will) do two things (1.Does it help the current vision of the startup? if yes, add it into the roadmap and get loads of user feedback on it by implementing the smallest experience you can of it to get the validation you need and the iterations you need for the problems your users have and 2. If it doesn't help then dump the idea, because not all ideas are worth chasing. I'd go as far as saying that Unless you have managed to solve peoples problems with your first solution (including through the hard work of repetitive iterations etc) then you should consider some learnings from your startup and focus on solving that problem identified. So stay laser focused. Amazon went from Books to CDs but stayed with books first, Apple stayed with Macs many many years before introducing another product line category... Just stay laser focused and solve the problems you have set out to do. Nothing else remotely matters. Don't jumble up ideas (snowballing them) or try to get unfocused by new ideas.
