Live your life, don't spend it. Live the moment. If you feel guilty about what happened yesterday, or are anxious about what might happen tomorrow, your energy will be dissipated. Reinforce the good daily patterns and break the bad.
Habits start as consciously made decisions, e.g., what time to get up.
Once established, good habits become second nature. Success is the result of habit. It depends not so much on doing the unusual, but on doing the commonplace unusually well. By concentrating on fewer priorities regularly on a fixed schedule, you can achieve a lot more in less time. This allows you to focus on fewer things and achieve more.
