Dear Teaching,
I see that you have made a whopping 193 posts

! I'm wondering what your posts concerned, and if you know so much, why don't you know the answer to this basic question? I also wasn't sure if your question was "What do YOU (the respondent) do for your self-worth?" Or "What does ONE (anyone) do for her/his self-worth?"
I don't know if I can answer both questions, because although I believe that there are some things that are the same which anyone can do to nurture self-worth, there are some things in particular that I do to nurture mine:
The former are, be your best self as often as you can. When you can't be gentle with yourself about it and just start over again the next day. This is in ALL areas of life.
The latter are, for instance, I don't have a boyfriend/lover/husband and haven't for some time; I love flowers, so I buy them for myself to spruce up and make my home (apartment) aromatic. I also have an extremely difficult life, by my lights, and I self-comfort, a lot, or else I would not have survived as long as I have. Sometimes I do this with food, but that is rare. I do it often by playing a lot of my favorite music, or watching especially inspiring or funny videos or comedy shows.
There are many, many other ways to nurture a feeling of self-worth (being valuable; if only to oneself) and self-respect. I also read a lot of inspirational books. Two good (little) ones for starters are: Life's Little Instruction Book and Life's Little Instruction Book II, by H. Jackson Brown.
If this answer has been helpful to you, please rate it, and also, depending on how helpful (valuable) send me a thank you payment! Cheers!
