To take good care of myself

When I was in my 20s, people around me often said 'you should take care of yourself more,' I didn't get it. I believed I always did what I thought was good to do : to help the others unconditionally, for example.

Now I realize I shouldn't have tried to help people who was not deserve to. And I should have helped people after I helped myself. I couldn't find what it is to take good care of myself for a long time, but now I found. Ironically, it makes me feel easier to help the others.
