Real life, good people

I love life. I love reality. I love nearly everything about, well, everything. There are, however, things that annoy me.
I am annoyed that I find it hard to accept the fact that there will always be someone out there who does not like me. I know that seems strange, but to me it matters. I am a Leo, constantly seeking approval, desperately wanting people to like me. I am likewise annoyed that I find it hard to admit that there are people out there I just do not like. Plain and simple, I am not required to like everyone I meet just like they do not have to like me. Why is that so hard for me to get? What is it about that concept that escapes me?
I am annoyed when, after giving many people the benefit of the doubt numerous times, I still get burned. I know that not everyone is going to live up to all expectations people have of them, myself included. I do, however, believe in constructive criticism. I believe that if people can dish it out they should be able to take it. I wish that more people would give me constructive criticism because I know I am not perfect and that I have a ton of room for improvement. Sometimes it is hard to improve if you do not know what you need to work on, and I invite a third party to let me know the areas in which I need to grow.
As annoyed as I can get, I am also heartbreakingly thankful for the wonderful life I have. I just have a few beefs, ya know!
