This tells me that you set goals that are realistic, practical, and obtainable and that your self-esteem is good, but not super high. The good news is your confidence is strong enough to leave a really bad situation and take those first key steps toward living your dreams. This tells me that you are a bit of a smart-ass. You see, sarcasm is a wonderful means of defending your ego. Often this sarcasm comes out as a wry sense of humor.
People love that.
But, if you're at all insecure, it can be directed at others and be a bit caustic and hurtful. Might I suggest that you bite your tongue next time you want to pipe in with a smart comment.
