I always love reading about experiences that are just brutally honest about the reality. Knowing that early will save the wannabe-freelance a lot of surprises, for when they want to do the same, they know what's going to be ahead of them.
Some outsiders may call that discouraging, and that's where the question of personal passion comes in. There are people like me who don't bode well with the standard employer-employee structure and work much better off self-employed. Reading honest experiences help us to predict what we have to do to get there.
