Why do you cheer so hard, defend so strongly for the person on TV?
Why do you feel so cheated when that person falls short of expectations?
Why do you get so angry and emotional defending them when someone says some cross words about your favorite TV star?
Why are your standards for what that person should/could do higher than the standard you have for yourself?
Because you don't believe in you like you believe in them.
And you wonder why you aren't getting the results you want.
