Why?!

Why is it that when I get aces in the big blind everyone fold to me?
Why do my suited connectors never match the board?
Why after a long wait I get a half decent hand like ace eight but the guy to my left has gone all in?
Wht does the river always seem to favour the other guy?
Why when I get kings there is always an ace on the flop?
Poker I guess!
But at least I am still ahead!
