I feel that people who brag about themselves or their situation are 1) are starved for attention and 2) are overcompensating for something. If you're really happy with yourself, your situation, your choices, then you don't need to proclaim to the world many times over that you're happy. If you have to brag, whatever it is isn't that great, you just want people to think it is. This can be a fine line - like arrogance and confidence always seem to be. On one hand, you want to share your happiness with others so that they can be happy with you. If you push it, though, you run the risk of sounding like you're bragging, and as I shared in paragraph 1, bragging is obnoxious. I think that you can be happy with whatever it is that makes you happy and your smiling face, welcoming persona, and open heart will automatically let people know where you are emotionally. Writing here, you obviously don't know if I'm smiling (I'm not currently), if I'm welcoming in my demeanor (not particularly at the moment), if I have an open heart (if you know me, I don't need to tell you this anyway - you probably know.)
On to the fine line between confidence and arrogance. Confidence requires poise and integrity, while arrogance is the easy way out - it's just acting like you're better than everyone else. It takes no effort to be arrogant - it just takes a sense of entitlement and the cajones not to care about anyone else. I'm quite sick of the sense of entitlement that my generation seems to have. Get over yourselves.
There's my serious post for the week. Take it with a grain of salt.
