Life is a journey, not a destination. We're all on a path to something - to get somewhere, to learn something, to change ourselves, to make others happy. We keep moving forward because we want more from our life than the ones we've already had.
It's easy to get stuck in the present moment - but that's where most of our unhappiness comes from. We don't realize that what we consider bad now will change in the future, and there's no point in thinking about it. The key is to put one foot in front of the other and move forward, even if it feels like you're going nowhere.
It's never too late to start doing things differently or better than you were before!
