Why am I so obsessed with this craft?

So I've been thinking lately about why I scrap. It has certainly taken on a life of its own within my own little life. I've always loved photos...looking through old photos....the stories behind them...the memorabilia. I used to sit at my grandmother's feet and listen to her stories and look at her photos....one of my most treasured memories of her. And certainly when I started all of this a few years back, my intention was to document those stories and photos and memorabilia. But I've realized in the past few days, that I scrap now for many different reasons- the documenting aspect of it is probably fairly low on the list. Scrapping has become my therapy...my happy place. It blows my husband's mind that I can sit for hours on end and scrap.....but I can....because that is how much I throughly enjoy it. I live for the creativity and the "play" aspect of it. I love inspiring others through my work. I love to get praise. And I've realized how competitive I am. And of course, I love to shop and buy more and more and NEW product! I'm sure as time goes on, my reasons for doing this hobby will change again.....I just hope it continues to provide me with as much pleasure and bliss and happiness as it does now.
