I'm pretty much my own worst enemy most of the time. I find it difficult to say nice things about myself. If this thread was about the 25 things you don't like about yourself, I would have no problem filling out that list.
1. My ability to put people at ease.
2. I understand why people are the way they are.
3. I am efficient, therefore effective.
4. I have a great sense of humour and take very little seriously.
5. I appreciate what I have because I earned it, not because someone gave it to me.
Interesting just how difficult this exercise can be.
