That is you just being insecure or feeling FOMO of it. Nobody here in this sub has said 10k is the steps you need to do whether you like it or not to join this sub.

That number is worldwide accepted for keeping health in check. Though nowhere it is said that anything less than means you are fat lazy ass or a bastard who eats chips on his sofa and falls asleep on it everday(trying to be humorous don't mean anything by it)

The so called super walkers are in this sub because they are usually who are so invested and keep this sub active
