Many Americans want to do so much that we feel we need more hours in our day. Since that is impossible, instead we need to figure out how we spend our time and if it's doing what we really want. A certain portion of our time is spent taking care of our house and our possessions, or reorganizing them or for shopping for more stuff. Thus owning too much can become a burden and prevent us from doing what it is we think we really want to do.
The key to feeling content in life is knowing what you want and to do that thing and feel satisfied. It is not a good feeling to try to do too much then fail at doing it all or fail to meet deadlines, because we then feel negative about ourselves.
We need to make time in our lives but stopping the doing of things that are unnecessary or extra or stupid or that are time wasters. There is nothing wrong with taking an intentional break from reality o watch a TV show or a movie but if you spend more time looking for stuff you already own so you can use it, or dusting saved things on shelves, you have lost time from doing what you want to do now.
We need to let go of old hobbies and stuff related to them because that stuff is in our face or in our way and preventing us from doing what we want to do now. Even if it is just visual clutter it is a reminder that "I failed at watercolor painting" and "Scrapbooking is a drag". Who wants to be reminded of the negative?
Today my game room has nice built in bookcases filled with homeschool high school educational materials. I already ditched the SAT prep books for the old style SAT that stopped being used as of this spring. But why am I keeping all that stuff when my last high schooler is in public school? I am getting excited at the idea of getting rid of more of it. While I am busy working on the garage I am psyching myself up mentally to be alright with letting go of the books we used and loved and those we used and hated or the ones we never got around to using at all.
Look around your home. Does it support the lifestyle you are living right now and those of your present goals? If not, start culling and letting go of the possessions that do not represent your life and your lifestyle. Make room mentally and physically to do what you really want to do right now.
