At a very young age I realized waking makes me happy. I know a lot of other exercises that burns fat more efficient, so I spent a lot of time trying to come up with something that justify a 2 hours walk. Eventually I stop trying to justify it. I just go for a walk listening to music. It may not be the best exercise for the body, but it does wonders for the mind.
