I believe I try to live my life in a very similar way. I believe there are a lot of us who try to do this. But I do not believe everyone does that. There are many people who are malicious and they know they are. Also I feel the same about pride and praise. In the past I was pointed out I hold myself in too high regard which can result in me beeing patronizing. And I try to work on that since then. Because I feel this is not right and I do want to strive for right.
Especially you wrote in comments something like: You try to do your best considering your environment, your own limitations and even your own weakneses.
So given that, I believe you are making one mistake. I would like to expand on your limitations part.
If you feel this behavior makes you forget your needs this in not “the best you could do”. This is the same as you forgetting to sleep.
If you are forgetting about yourself like rest, having fun, eat properly, maintaining your mental health. This is not your best or “perfect behaviour” in long term. Because of ignoring your own needs you will not be able to do your best tomorrow or in 10 years or will live few years less to do good or you will not have friends or be part of a community to achieve even better things together. Something like that.
Also another thought popped in my mind I do not have an answer for and I would like to see your perspective on that. I try to avoid as little responsibility as I can. And I see myself as one who is trying to do his best. But. But when I look on myself objectively I live quite a normal life: I have a job and a family and some hobbies. I try to be there for my friends and family. So asking myself. How is this the best I can do? I am not volunteering or anything like that? So is this “feeling” I am trying my best just a cover for comfort, so I do not have to do some real sacrifices for community?
This probably makes the most sense. Although thinking is easy. Doing stuff is hard.
