Very true what Paul says here. I have created two companies on my own(backed companied from others). The first one was Hell, nobody believed in us or the idea,

Very true what Paul says here. I have created two companies on my own(backed companied from others). The first one was Hell, nobody believed in us or the idea, everyone believed I was crazy, and after fighting and loosing battles a lot I also(my subconscious mind) started believing it!!(I had trained it in failure) But then it turns out it was a brilliant idea after all. We were the first surprised to see that in the end it worked even better that what we devised at the start. Everybody loved our product and people that had down played us in the past were telling us how much they "always knew" our idea was going to succeed. The second time everything was objectively very similar to the first company, but it felt completely different. The experience of success gives you confidence and makes things very easy and even fun.
