I was asked this question recently and here is my answer:
If you feel you have wasted too much time, then you have wasted too much time. It is your choice.
On the other hand, you could think:
“How wonderful! Every minute I have spent on this planet has made me the person I am now.”
And now the most powerful part:
You get to decide right now how you will spend your day and who you will be today.
So, what gives you purpose and joy? What gives you energy?
Ask yourself: In a year from now, what would I like to have accomplished? If you did a post on Quora in a year from now and you said “I have had the most amazingly fulfilling year”, what would you be talking about?
