Time travel is overrated; practice being present. Don’t let your fear of wasted time cause you to miss it altogether. If you slow your mind, you can access eternity in a moment.
“We are always amazed by [time] – how fast it goes, how slowly it goes, how much of it is gone. Where, we cry, has the time gone? We aren’t adapted to it, not at home in it. If that is so, it may appear as a proof, or at least a powerful suggestion, that eternity exists and is our home.” C.S. Lewis
