Don’t just put it off a little bit longer, do it now. (Even if that little bit longer is just a few minutes, and what you’re trying to do is wake up.) Don’t take care of it tomorrow, if you’re passionate now, do it now. (Even if you have a schedule to keep, or need to sleep – take care of it now.)
There’s no next time. It’s now or never.
Do it now, because if you don’t, you’ll never.
