I hear he feels trapped, being a parent, and a responsible adult can do that to you.

However, I raised two children, spent hours reading to them every night, feeding them at 1 am so that they would sleep in until 7 am. But there were four glorious hours every night between putting them to bed, and going to sleep myself. During that time I developed side projects, read, and enjoyed myself. I suggest the author try to relish the time he does have, rather then feeling trapped.
