Past is a notion,it no longer exists and sadly nothing can be changed about it.Do not brood over it time and again, you feel despondent.It can only be a guiding light.
Future is unknown – without an objective it’s meaningless.It’s always uncertain.One could only plan for the worst which is important.Have a contingency plan – plan ahead.
Present is now and now is neither past nor future it’s the timeless reality.If you have today in your hands,it’s a gift and hence it’s called present.Grab it,you have the power to make it happen,to evolve.
