Focus on what you can control
Most of the time, people are vexed and carried away by the things they have no power to influence or change. They end up wasting their positive energies.
It will marvel some, the extent to which they can exercise control
You can control your thoughts, attitudes, character, choices and so on...Focus your energy on these and take charge of your life.
Let go of the things that are out of your power.
ExActly. Efforts and Energy directed at controlling what is beyond us are wasted !
