This may sound stupid

But I’m genuinely and seriously asking. How do you be less selfish, but at the same time stand up for your wants and needs? I am struggling with balancing both. I tend to be selfish, sometimes without realizing it. It is definitely a faulty characteristic of mine, but I want to be better and do better. I’m struggling with balancing it out. I don’t want to allow myself to get walked all over, and have my needs neglected in the process, but I also don’t want to be too selfish. So seriously, how do I balance this out? If ya’ll have any tips, I would greatly appreciate it. TIA.
