Like most people I can be lazy, so it's nice to have a goal or deadline or reason to work out. I feel better when I get to exercise, or when I'm outdoors. I like to hike, swim and run, and I love to play soccer.
There's no excuse to be bored. Sad, yes. Angry, yes. Depressed, yes. Crazy, yes. But there's no excuse for boredom, ever.
