If you live in regret then the past controls you. Regrets leads to disappointment.
If you live in anxiety about the future then you have no control. Anxiety leads to discouragement.
If you live in the present and take whatever actions you are capable of today then you have control. Presence leads to power.
The Truth About Time
The past is gone.
The future is out of reach.
Now is the only time you can do something about your life.
