wjw, I personally think the "textbook" methods of time management and goal creation are overall a waste of time. You know yourself the best and the things you like and need to do in a day. Figure out a flow that works best for you.
Forums and online games are not exactly bad - I think that some people who will tell you that in the self-help department get a little overzealous in their quest to be "happy." I'm not going try and tell you to be
balanced either because I think overall that's a widely abused and ambiguous term that doesn't really clarify anything. Rather, consider this idea: If there's nothing in particular that you want to achieve - who is to tell you that you should? It's your life, it's up to you.
I know this goes against the grain of what is popular in the self-help industry, but I think "getting yourself motivated" and doing other little "techniques" that other people came up with is mostly a waste of time. Try some out to get some ideas to play with, but work with what you figure out works for you.
