Attitude & Skills: What i know and what i don't

The definition of attitude is unclear to me till now. there's always something that i do not know or i should know.
i call it natural behaviour. most of the people i have seen have different attitudes. All of them are unique.
we start judging them or trying to change them as we like.
what we should understand is we are all complete in ourselves, just some polish is needed which time will provide us.
Our skills will become stairs to better future and our attitude is a step to our better selves, if we stick to it.

I'm new here so apologies for mistakes. Thanks
