consider that you may not have an adequate nail polish collection. some are old and smell like glue. throw those away and get these three colors, and these three colors only: red, black, and clear.
consider that you have maybe looking with intention will bring you happiness. a flower growing from a crack on the pavement. a dog making a funny face. two lovers happy to see each other on the street. what's there not to love?
if possible, get yourself a place to think. it doesn't have to be big, but it has to be yours.
make a note every day of at least five things you are grateful for. it doesn't have to be complicated: you can be grateful for the sun.
your clothes don't fit you? that's okay. they don't fit me, either. don't go out and try to punish yourself for changing.
practice not talking to yourself for a couple of hours. enjoy the silence in your head. embrace it.
remind yourself that time on this earth is a gift, and you might as well enjoy going through it as well as getting over it. the gift of feeling our emotions is not something that should be understated.
