Sometimes I find that my life begins to revolve around my future. Why am I doing that? For a better future. Why am I stressed about that? For a better future. Why am I letting that bother me? It determines my future. In the time that has passed since you began to read this, we are already in the future. It is a reoccurring cycle. Honestly, though our futures' are important, focusing so intently on them can make it pointless to be planning for the future in the first place. Once you get there, you will still be planning for yet another future, and you will not even be enjoying the moment that you previously planned. How do you know when to stop? I know for myself. I try to stop when my plans get too specific, because I've realized that almost always they don't ever turn out specifically as I plan them.
I am not saying don't plan for the future. I am just reminding myself, and you, to enjoy this moment, the now. Although we may not understand it, this moment is full of so much life, happiness, joy, and amazement. All we have to do is look for it. Dream, fantasize, and go ahead and set goals, but don't let those things take over your life.
Remember, future on Earth is promised to no one; we are all eventually going to die. In the next moment we may be gone, hopefully we enjoyed it, instead of fretting about a future we were never going to have.
