2. Make a daily schedule and stick to it

Achievement rewards routine. 

As an extreme example, consider the early morning schedule of Apple CEO Tim Cook. He gets up 3:45 am day by day, guaranteeing that it permits him to traverse the 700 or so messages he gets every day, and gives his time to work out before he goes into the workplace.

By setting an everyday routine and adhering to it, you'll see that after a while, it's easy to make time for things since it turns into a habit.
