The two main themes of this blog are freedom (living the life you want) and responsibility (making a difference). When you think about it, these two are also what we're trying to achieve in this life. If that's the case, are the things you're doing bringing you closer to your freedom? Are they making a difference?
If not, then why are you doing them? Don't worry. I know your reason is very important too. It's just good to be clear why you're doing what you're doing.
"All religions, arts and sciences are branches of the same tree. All these aspirations are directed toward ennobling man’s life, lifting it from the sphere of mere physical existence and leading the individual towards freedom." -- Albert Einstein
