The past and the future are composed of now energy. However, the two states of time only exist in memory and imagination. If you have some of your now energy allocated to the past, you are likely inhabiting your memory and thus experiencing regret. If you have some of your now energy allocated to the future, you are likely inhabiting your imagination and thus experiencing desire.

Both the feeling of regret and desire can cause psychological pain. Forgive your regrets, life is too short. Cast aside your desire, because you can have it when you get there, but not until. To get relief from this pain, we have to shine our light of consciousness onto where our presence is allocated. With this understanding, we can have good reason to occupy the moment, forgive the past, and let the future come when it may.

I hope this helps some, I have short bursts of lucidity from time to time and can give great advice but can't take any of my own. That makes me either an oxymoron, idiot savant, or full of shit. I'll let you come to what conclusion you may. Here's a couple more thoughts on time and the nature of desire.

P.S. I know that I'm not telling you anything you don't already know. I just wanted to give you a couple of logical tools for why to be in the now, and that's mostly because inhabiting the past and future can be detrimental to our state of well being. We all get stuck in the muck now and again. You may have read this before, but it's good to read from time to time, mostly though, only when times are rough.

To answer the leading question, I ran out of fuel and the black hole ate me a long time ago. Now I just back float merrily, merrily, occasionally despairingly, life is but a dream. But you know what you gotta do, you gotta row that boat, row it till the ores fall off, or just let it float, there's no right or wrong way to do this thing called life. Fail the required amount of times that it takes in order to succeed.

Problem is we keep winning minor victories day after day and then easily over look them as if though they never happened. The desire keeps moving, and we keep chasing the fix. There is a fine line between not wanting to do anything (boredom or despondency) and becoming desireless (contented or just okay as is). They're the same but different, all you've got to do is walk over that line from time to time to restore the balance.
