"Then I was young and unafraid
And dreams were made and used and wasted
There was no ransom to be paid
No song unsung, no wine untasted

But the tigers come at night
With their voices soft as thunder
As they tear your hopes apart
And they turn your dream to shame"

If we only react to everything that happens, then we will never get to do anything we want to do.

Do not allow the events in your everyday lives set you into thinking, 'how do I react to the situation?'.

Put the past behind, be it good or bad, pleasant or not, and remember that there is nothing you can do about it. Rather, think about the things you want to do, in order to live the life you want to live, and more importantly, have the wisdom to know what you can do and cannot do.
