This selfish attitude is what landed most of us in the gym in the first place. The gym is like a purgatory for vanity.
"I'll just mind my own business, even if I see someone I could really help... unless they ask."
Imagine if someone had helped you when you were a kid. Maybe you wouldn't have fucked up so many times. Maybe you wouldn't feel so unaccomplished and weak. And, maybe, you wouldn't feel the need for a shiny muscle suit to drape over your inner worthlessness.
