People who think they are really good/great at something often just haven’t met enough people who are better (although not through lack of those people, just limited exposure to them!).
There are plenty of people who will surround and compare themselves to family/friends/colleagues who don’t do something as well as them, then they feel “good” at it.
For example, I used to think I was good at snowboarding, even during a season I was in the top quarter or riders. Then I started riding with people who are a different level (two GB riders and a load of people who pay the mortgage riding), and I realised just how average I was.
I have so many passions, hobbies and interests, but I would reckon I’m average (at best!) at most of them.
there’s days at work when I wonder how i ended up doing what i’m doing and that it’s only a matter of time before i’m responsible for a £££££ cockup. but then there’s days when i’m utterly brilliant. Does that mean I am good or bad at my job? 🙂
It’s all relative innit.
