As the saying goes: If we don’t do it Now, it will Never be done.
Is it really true?
How about doing it when it comes to you, doing it with precision, doing it with consistency? I believe there is no point in being fanatic about doing it now. Do it when you believe in doing it.
Hence don’t worry if you missed things in life and regret that time has gone by. It will come again and that time you will be better prepared to do it.
So in life it’s more like:
Now or Whenever!
