If you are deppressed, you are living in the past, if you are anxious you are living in the future, if you are at peace, you are living in the present.
Go out and walk. That is the glory of life.
Here we are, trapped in the amber of the moment. There is no why.
Doing the best at this moment puts you in the best place for the next moment.
Do good and you will feel good, it is that simple.
