I just came up with an analogy of trying to be successful at startup: Imagine someone who is just born in prehistoric rugged terrain who wants to reach some magical place. You don't know even how to crawl. There is some food and clues all over the place about how to reach the magical place. You have a magic button which can take you to slave house (corporate life). You could potentially come back from Corporate life to the startup life, but you would be bruised and would have picked bad skills which you know needs to forget.
You immediate focus should be gaining skills and pace. You will start by learning to crawl, walk, jump, climb, track your path, get better instincts, find food, look for clues, follow clues.
With more tries, you will get better at these. You will be better at navigating the terrain. You will get better heuristics which will determine your success.
Many time either people looking for a magic solution. This is equivalent to someone in this situation thinking if they can roll downhill and hope to be within crawling space of the magical space. It doesn't work that way. Some people do get lucky but most don't.
Any many times people are procrastinating. Which is like someone waiting at the edge of this magical world figuring out whether to make a plunge.
Just get started. You will figure out along the way. Make sure you have a good plan on health and finances!
