I’m trying to give good advice in a soft form, but I have a firm position on this issue: if you are in doubt or afraid, do not start anything at all. Running private business is difficult, you face challenges every day, you have to constantly overcome fears. I believe that you are either born with an entrepreneurial spirit, or you make a huge effort to open a business because you REALLY want to. And if one thinks to develop a startup simply following modern trends, supposing that nowadays success can be achieved only this way, while not feeling 99% confident, then it’s not a game worth playing.
