What we spend our time on is what we value, I think some people lose sight of that and think they have to spend their time doing something, or deserve to spend their time relaxing after work, but everything we do leads to something so if we aren't putting forth effort we will probably end up stuck where we are, which could be good or bad, usually I like change though.

Sometimes we don't get to use our time on what we want, most of us work most of the day and have other responsibilities to boot, doesn't mean we can' spend some extra time to get where we want to be.
