I write quotes and things I hear and read that strike me as interesting as well. Being outside in the sunshine is also helpful.
Sunshine is very uplifting and soothing.
Treating myself to a hot bubble bath, or a new hair do or a trip to the mall to window shop. Get out of the house and go somewhere else - even if it is only for a few hours. Going out makes my HAVE to care and can be uplifting. Do not be afraid to ask for help with kids or housework - it makes you feel better when your space is clean and neat and the kids are out from under your feet for a while. Pray - and God's word.
