'Smile' says the sign, so 'smile' I shall.

If you don't know what you're doing now, then how do you know what you're doing later? Having one setback shouldn't stall everything around you, you need to push forward and use that to your advantage. Having one advantage may be the only thing you need to succeed. Use it then do what you've set you're mind on in the f...irst place. I think that's what we all need to do. Now. Not later. Later might be too late.
