alot, a lot, there, their, they're, your, you're

these are the words that I cannot use in correct context for the life of me. (I know that alot is not a word, but I still use it, in fact I use a lot very often) :)

Does it make me a hypocrite? I mean, should I have to live in a world where my boss cannot spell routine, and then he misspells it like 420 times? yet, since I can't spell "a lot", I am a hypocrite? (PS- I can't spell hypocrite either)

Well, I'm done on my little spelling defense, peace out-
