Actually it is easy for someone to spread the theory of problem solving, what is more important is the practice. To be honest, I'd rather read the inspiration of the founders of the companies tagged in that thread because it's clear they have experience building startups from scratch in their current state than some random guy behind a twitter account who hasn't necessarily done anything great.
In essence, if you want to start something that deals with money, then learn from people who are really experienced. At this point you will be risking one vital thing that cannot be returned, the time.
I have been reading discussion of a certain group for startups.
And timing is part of it, ideas are there but one thing for sure that they put as the matter of importance and that is execution. Let us say that many of these startups built at the right time and became unicorns. But it doesn't mean that all of them are going to be successful in the future. I have seen startups that were funded well with huge amounts of money but now, they are nowhere to be found.
