The hardest part is the loneliness, ppl dont realize how hard is to be the captain of the ship with nobody to even give you their opinion, its not what you do but what you know, learn and apply, I went through that experience and was not able to deal with it so got me a job, still have a few clients on the side but have come to value my job, consider it doesnt pay all my bills and Im mostly and IDLE IT guy because everything just works, but the mental and psychological weight is heavy, one way or another there is not escape from work, everything that becomes repetitive turns in to work even making money with money.... stay on the fight keep it going ✌️💪
