Throughout my 20s I spent a lot of time just playing and not really working but fortunately for me I continued to get just enough work and have a reason to wake up in the morning. I really empathize with some of my peers who had success in the early years then it dries up and so there's no reason to get up in the morning.
Every job has its downside. For example being in a band the travel part of it - getting picked up from your house in a car going to the airport getting on a plane going from the airplane to a van then going from the van to a hotel.
