If you set aside the things that cannot change and stop fretting over them
, that will leave you with the items that need to be a concern of yours. By handling them one at a time, considering that the others are going to wait until you get to them, you will be able to eventually get through the list and to deal with the stress more successfully. If you are able to do this, it is a method that you can use for the rest of your life to successfully handle stress.
