Can we predict and plan our future?

We all know that the future is essentially unpredictable and uncertain. Even when we plan well and follow our plans precisely, we can not control unexpected events.

Mahatma Gandhi said - “The future depends on what we do in the present." 

Instead of worrying much about the future, we should have an optimistic outlook of it, by doing positive things in the present...that is here and now. 

"The best way to predict the future is to create it."  - (*) Quote credited to Abraham Lincoln and Peter Drucker on diferent sites.
