Time and wasting it

Time, the thing we can not control and the thing most of mankind is wasting. We can't turn back time but do we want to turn back time? Cause if you didn't do this or that you wouldn't be the person you are today.

Example: If I continued playing tennis I may be the best tennis player of the world but maybe mine personality would be hated or something else. But I wouldn't be the person of today.

So in place of being angry of the time we wasted do it good in the future but what is good in this sentence? Does it mean like the tennis example train every day 5 hours and thou shall be good or must we do something we can enjoy like computer gaming/sleeping or a mix of both.

In the end it will all come down to the mind and what we think about it, if we think we're growing we're growing(if the right action and feelings are applied).

Release the future like releasing a pen, plan for the future to know where your boat is going(What if you don't have an idea where you're going*) and focus in the now cause here is where all the magnificent things happen.

*If you just release your boat you might find a treasure or you might fall of the edge of the world. But there are more edges of the world then there are treasures, or at least in normal human minds.

Question it yourself
