a. Anyone here works hard to make a living.
b. Anyone here uses his brains to make a living.
c. Anyone here makes a living by using their intelligence.
Are the above sentences grammatically correct?
I use 'everyone; and not 'anyone'. I don't see a reason why 'anyone' would be wrong, but the sentences do sound a bit strange to me. I know I asked a similar question recently, but I am just making sure.
