I don't know what the future is, but you just do it whilst it's there, don't you?

dont wait for next minute, next hour, next day, next week, next year, just do it if you want to do it...

I just have work to do; I just do it.

I just sort of go along and say what I think -and that's all you can do in life, really.

If you want to do something, just do it. No one is going to do it for you.

There's doubt in trying.
Just do it or stop thinking.
