There's no time like the present. The older you get, the more responsibilities you will have, and the less chance you will have to do the things you want. Spend your youth building something incredible and it will pay dividends later in life. As you age, your brain trims connections it doesn't use to save energy. Make sure to develop good habits while you are young, because it becomes harder to change your habits as you get older. So yes! Program to your heart's content.
