Sometimes you might focus too much on your past. Think how would your life goes if you do things differently. How would it change if you would do this or that?
Thing is, that living in the past will not bring you anything. It is ok, to go back, to the experiences from the past. And use them as a lesson for a better future. However, it is not ok, to focus on the past. And contemplate all possible outcomes of the actions you already have done.
Another extreme you might tend to go into is to focus too much on the possible future. Not on your goal, your dream future to which you follow. But on the possible things that could go wrong. Or just on daydreaming about it. This is not good to.
One of my favourite sentences says:
“Yesterday is history. Tomorrow is a mystery. But today is a gift. That’s why we call it present.”Master Oogway
We live now. And this is the time and place we should focus our minds and efforts. Forget about bad experiences from your past. Learn on them but stop playing them in your head over and over. Spend some time daily to think about your goal, your future. Imagine it for a few minutes. To have a clear vision of what you want to accomplish.
But live here and now. Focus on things to do now. To achieve your goal and finally live life from your dream.
