Do not dwell in the past, do not dream of the future, concentrate the mind on the present moment.
Life gives you plenty of time to do whatever you want to do if you stay in the present moment.
I know that the purpose of life is to understand and be in the present moment with the people you love. It’s just that simple.
The best gift we can have is living in the present moment and really enjoying it for what it is; and, not being in our heads and getting sidetracked.
