In life we all worry about what other people might think about us, but the truth is that we journey through this world largely anonymously.
Nobody really spends time thinking critically about you; they can't really remember what you said 'that one time'...even if it was a particularly stupid thing to say.
The great news is nobody actually cares that much about you, everyone else is actually just preoccupied with their own worrying about 'what other people aren't saying about them'.
So do what you want to do in life, stop editing your behaviour and yourself. You don't need to impress anybody, because there isn't anybody paying that much attention to you. You are freer than you think.
Nobody is looking, nobody cares and nobody remembers in any case.
