Very well said. Life is short. Do what you like.
And at times a forced move from your employer makes you rethink and achieve higher goals. Its a difficult decision to quit or cut short on an in hand job by yourself. But when you are forced out by the employer itself then you don't have a choice. That's exactly the fight back time.
There is another important point which I would like to make,
'Anything and everything in this world is replacable'. Nothing should be taken for granted.
