I am 32 and I am still searching for my passion in life.  I have always liked a little bit of this & a little bit of that.  But, I never have focused just on one thing.  The closest I have gotten is my passion for spreadsheets.  Terribly boring, I know.  I still really do love spreadsheets, but don't spend too much time on them these days ( I am now a stay at home mom ).
I think part of my problem with finding my passion in life is that I must have a little bit of ADD.  I just cannot seem to focus on one thing long enough to really dive into it.  Other than spreadsheets.  Maybe I was able to dive into spreadsheets because it was my job.  These days I don't have enough time to truly dive into much... besides elmo & the wiggles.
My most recent venture is an online stationery & invitation store.  It's led to many strong interests, but not one thing has stuck. I really got into SEO (search engine optimization) for a while there.  Then, it was learning html and css.  I moved on to learning to use Photoshop Elements and have dabbled in some very amature graphic design.
Recently, I've been trying my hand at digital scrapbooking.  I have no real clue how to scrapbook digitally... but as with everything else, I am trying to figure it out on my own and learn through my mistakes.
