We are the designers of our own lives. We make all the decisions, good and bad. It's easy to look at your life as something that happens to you, instead of something you're in charge of. The truth is, it's up to us whether we participate in life, or sit back and watch it pass by.
Perhaps you're thinking to yourself right now "yeah, someday when I'm not so busy, and I have more time, I'd really like to spend more time enjoying life." But nobody knows how much time they have on earth. It could all be over in another eighty years, or before the sun goes down today. There are too many unknowns in life to assume you can do things tomorrow, or ten years from now, or when you retire maybe. If you really want to get into the game, shouldn't you do that today?
If not now, then when?
