You know the saying "Being a big fish in a small pond"? I do hope you are feeling like a big fish in your life, because we all are meant to be big fishes. I'm a HUGE WHALE for my son and hopefully a big fish for my family. I do enjoy a big fish syndrome in some other areas of my life as well.
But here's the thing -- you shouldn't feel like a big fish in all the areas of your life. That just shows that your pond has started to limit you and it's getting critical to raise your standards or wave goodbye to a fulfilled life.
It might be a good time to see if your perception of yourself is really honest or is it just reflecting the limiting expectations that "your pond" is setting to you.
Before leaving to Malaysia I was enjoying a rather comfortable life in Estonia, had a rather strong self-image and even though I was challenging my comfort-zone regularly it never got to a critical point where my self-image would have got seriously challenged.
