Q&A: Always having a coach

My question is regarding coaching itself. It is cultivated online that you need a coach all the time, otherwise, you are not growing (or even worse, you will fail in your online business). Although offline I know many entrepreneurs and they don’t have neither coaches nor mentors and are growing perfectly ok. So, what is you take on this? Do you think coaching is needed all the time? Do you have your own coach non-stop?
