Is it okay to hate myself for being imperfect?

To be honest with you, everyone has the same feeling that you are experiencing. The only difference is the degree of said feeling. Within our subconscious we have a need to satisfy others, and as you said, you can't satisfy everyone and if you do try it will drive you crazy. My piece of advice that I can safely give you is to find what is important to you and prioritize those things over what isn't as important. I believe through this method you will accomplish more things, thus improving your self-esteem and in the process you may learn how to not only do those things that are important to you well, but also learn how to incorporate those less important things into your life without compromising the things of importance. This is actually my first answer in Yahoo Answers so I hope it helps you in some way and possibly helps anyone who reads this.
