It is very easy to expend all your energy worrying. Concerns about past mistakes, rehashing what you should have done, revisiting occasions of sadness or anger expend time and energy. Many people think of the future with anxiety, anticipating problems that they may not be able to overcome. Losing sleep, feeling on edge, and stress.
One way to get out of the worry habit is to heighten your awareness of the present. Things are happening all around you every minute of the day.
In holding onto moments and memories, it's essential not to get bogged down in the idea that they are more valuable than what you are experiencing right now. Remember: the only time you really, truly have is now so it's pretty pointless to waste time dwelling on the past or worrying about the future.
That being said, I do think it's important to keep some particularly special moments, even as we live our lives in the present. There has to be, as with most things, a balance between remembering the wonderful experiences we've had and remembering to enjoy the life we're living right now.
A lot of the time we can find some of that good from our memories in the moments we're living right now. Take the time to look around and notice what's happening in your current moments to see if there are any of those memory-making qualities.
Memories all start with a moment and it's important to realize that all moments will someday be memories.
