If you are having trouble letting go of things for sentimental reasons it may be time to move on. "By keeping yourself in the past you will never let go," Peter says. "The stuff is like an anchor—you have to hold on to those memories because they are what has made you who you are—but you have to start putting those things in perspective so you can move into life as an adult."
Peter says to look at the stuff from the past and learn to separate the memory from the object. Instead of holding on to things, take a photograph of items and make a memory album. And, you don't have to get rid of everything. Choose one or two items from your childhood collections to keep then sell the rest. You can take a trip with the proceeds!
