Too late?

I'm afraid that you wont change , that you will be stuck with your current flaws (which are many) ,and I do like you ....you are interesting , cute,and have so much potential .....but it's hidden inside these brick walls that you have build to shield you , you are way too insecure and really you do have some ugly flaws that you should work on , you are over 20 and they say that whenever a person gets older it's harder to change . I just want you to stop being insecure and be yourself and you know about the rest .
