There comes a time when you need to step back and rethink all your different priorities. This has happened to me and I have had to rethink some of my goals as well as my priorities. I was one of those people that had to please everyone in the past and I didn't care if I was happy or not. Doing this causes a lot of problems because you don't really feel happy when you are doing some of the things you have agreed to do.
Being able to rethink your goals is a project in itself because you have to think of why are you aiming for that specific goal, was it to please someone else or to please yourself. It does take some time because it can also mean redoing the goal so that it is more for pleasing yourself. Some goals just get deleted because when you realize you aren't going to achieve it and be even a bit happy there is no point in doing it.
I was one of those people that had to please everyone and I would forget about pleasing me. I came to realize that there are some people that no matter what you do you will never please them so why try. This step was a huge thing for me to realize and since doing that I have felt better and have given up trying to please these people.
I now have goals that are for me and also to help me be happy. I am not saying that you put yourself first all the time, I am saying you need to remember to do things that please you as part of your life. How you feel is very important because if you aren't happy you can't really make others happy, or at least the people that count.
