"Think of your many years of procrastination; how the gods have repeatedly granted you further periods of grace, of which you have taken no advantage. It is time now to realise the nature of the universe to which you belong, and of that controlling power whose offspring you are; and to understand that your time has a set limit to it. Use it, then, to advance your enlightenment; or it will be gone, and never in your power again."
---Marcus Aurelius, Meditations

That pretty much sums up where I am right now.
