Great thread!
I accept...myself. I accept who I have become over the years, and while I know that there is something I can improve on, I accept that.
I accept that, while I have made a lot of mistakes, had done wrong to me a lot and have done and said a lot of things that I would otherwise regret, I realize that people make mistakes...but then I also realize that you can accept what you did wrong, and resolve to make that mistake a lesson. I have accepted all my past flaws, my present flaws and move on. Change as I need to change.
I accept that my life isn't where I want it to be, and it's extremely stressful. I know that it will get better, and there is a definate plan to get it there. I accept that I just need to change some things, and follow through with it. I don't feel bad about it anymore. That just hinders me.
I accept my husband. He's not perfect, nobody is. But I accept, and sometimes (sometimes not) love his flaws (which is really charachter, in my eyes). The flaws I don't love, I understand that he's an individual and there isn't anyone in the world who can make you happy ALL the time. The important thing is that they make you happy at the end of the day, and you would lose a part of yourself if you ever lost eachother. I accept my husband full-heartedly and I don't try to change the things that define him...even if they can be a bit annoying.
