Just remember. We are here, now. Not tomorrow. Not yesterday. Right now.
No matter what your decision is, it is one you have to make. But remember this: the time we have on this planet is very short. Right now, at this very moment, you can pick up a phone, or get on the computer, and tell someone you love them. See how they are doing.
Nothing is guaranteed in this world. But one thing we have is this very moment.
Don't waste it.
