Won't squat without a spotter? disappointing kp

i love the fact that with squats, it is actually (sort of) a matter of life and death whether you make the reps! I've never failed a squat and i don't plan to, i just work the weight up slowly and never go for reps i don't think i'll get. I just think if i ever can't get the rep, ill fall backwards onto my ass and hope i don't break my spine
