Achievements and Competition

Thank you.
     I sometimes look at my Gamer Score on my 360 (because I can't afford the One) and think that's it is super low compared to some of my friends.  Actually, almost all of them.  I see myself as a really competitive person and knowing that they have some odd amount of points above me really irritates me - especially because I don't have the money to keep up with them.  Or the time it seems.
     Now achievements in games may not count for much (if anything really to most other non-gamers) but they still make me proud to a certain degree.  It's nice knowing that I beat x-game on a certain difficulty and there's a little brand for all to see.  As for other achievements... I've noticed that I have become slightly addicted to Tumblr.  Even more recently I found out there are achievements which seems odd in the micro-blogging world?  You even get little trophies, we'll say, for x-number of people liking your posts or sharing your content (which isn't hard if you reblog anything you like - it's bound to happen).  Which one seems more brag-able to more people? 
     This makes this post sort of random, you know?   Just some thoughts before I trot of to bed after maybe a map or five on Awakening.
