It’s all in your head (via xkcd, one of my favorite online comics):
Sure, there are practical limits to what we can do, especially when our actions affect others or when they require great amounts of effort, but almost everything we do in life is what we choose to do, bot the good and the bad. So, if you’re not doing what you want to be doing, ask yourself, “why?” It’s very likely only you know the answer.
