The past won't come back. Forget about time machines.

Guilt won't fix anything.

Putting things off til tomorrow will only make things worse.

Perfect results won't ever happen.  Stop wasting hours on details that won't make a difference.

We only have one life to live.

Studying, planning, it's ok, to a point.

Getting everyone's approval before moving forward ? Useless. You will always find a naysayer.

You get my meaning, right ?
