How not to abandon oneself

Hey guys, I want to ask if you have any strategies how not to abandon/betray oneself. What I mean is I often find myself disregarding my needs. Especially when doing something for other people or when it involves other people. Even such seemingly silly details like not dressing myself warm enough when it is cold outside. I know there is a voice telling me "it might be cold, check the weather and dress accordingly", but often the voice is too weak or I disregard it. I am working on it and sometimes it is better, but often not. Do you have such experience? What do you do to avoid this?

Sometimes in the morning I make a list of the things I should do that day. I find that if I write it down, I'm more likely to do them. And maybe after you've done something you need to, you could do something to reward yourself. It can be something simple like a treat or listening to one of your favorite songs.

One thing to do might be to consider how you would advise someone else in the same position. Sometimes it's easier to be sympathetic to the needs of someone else than your own, and thinking this way can help you to see the validity of your own needs.
