What specific thing have you done that impressed yourself?

In what area of life do you mean? Relationship, Love, Personal, Work, Humanitarian...
With so many dimensions to life, I'm just a bit perplexed by your question.

There is no limit as to what area it was in, just as long as it was something you did which caused you to be impressed with yourself. Did you climb a mountain when you never thought you'd reach the summit? Did you beat cancer that you thought was a death sentence? Run into a burning structure & save the occupants? Or even something as simple as losing weight & keeping it off.

I didn't want to limit it, but I didn't expect many people to be self-impressed with all that much maybe that's because I'm so self-critical! If it makes you more comfortable, go ahead & break it into categories or just mention the top one, the one that MOST impressed you.

I find the things that I remember most about school, are the times like those, connecting with my friends, not the countless hours studying & sweating over exams & papers. Sure, I remember those, but they all blur into a continuum. The individual, bring a smile to your face events, are the in between times spent with other students.

I like your example!

Oh, the O's! Good for you, I think I have yet to find all of mine & what a pleasant discovery it was that there were more than one kind!

Thanks for the thoughtful answer!
