I think you have to be a little selfish so that you can be less selfish. For me my alcoholism was all about me being selfish, but, ironically, to get better I had to focus on myself. I got sober for my kids, my wife, and my grandson, but I really got sober for me. So I could be healthy, so I could be there in the future, so I could be happy.
I know that's a lot of I's, but if you don't take care of you there will be no I.
That's the way I see it anyway.
