We've already invented The Time Machine.
Yes, we have. However, it's not a box that you can step into and zoom to the past or the future.
It's in doing what you love.
Have you ever noticed that time flies when you're enjoying yourself? Like when you're with someone you love or maybe doing something you love.
Fill your life with such awesome people and work and you'll never be bored of living. You'll pray to have more years added to your life bucket.
Don't waste your time doing boring stuff. Make life more exciting.
