By doing activities and being around people you like and even love! For example this weekend I spent time painting, and just appreciated the process. 

Too often we all spend time doing things we believe we "have to" and tolerate people that are not pleasant because its "the nice thing to do". I've been guilty of this, feeling like it made me a better person to try to fix, and have patience with people. Honestly that is only protecting my pride and hurting myself, and possibly the other individuals in the end.

Really what has to happen is you have to stop making yourself be at the mercy of others, and learn to be comfortable with not meeting everyone else's expectations. It takes time to get to the head space of this attitude being comfortable, especially if this attitude is a habituated pattern. While making change, remember to take it moment to moment.
