Life is a process, and you just take it a day at a time, and you can't live in tomorrow, and you can't reach back and be in yesterday. No matter how much you want to, you just have what's right there in front of you.
I think what I mostly realize is just that life is unpredictable. So don't be afraid, but just enjoy the day you're in. Really make the most of it.
Anybody who's ever gone through a hard time - any outsider's perception, no matter how much information they're given, they have no idea what the person's life is like.
If you went to your closet today, would you pull out the same outfit you wore 10 or 15 years ago? You wear feelings and faith differently as well.
