I'm so glad you asked Nataly!
I have my purse:
This houses my things that I take everywhere. Wallet, checkbook (who uses those anymore!!), small brush (can't have crazy hair!), tampons (do I even need a reason?), sunglasses, lip gloss, chapstick, compact and my MP3 player.
Then there is my laptop bag:
My life, as I call it. Of course, it houses my laptop, but it has my other professional needs when I suddenly come up with the answer to a coding problem that I've worked on for a week. I use my laptop as my primary workspace at work and at home, so I carry it with me everywhere. So, in there of course falls the network cables, the disk pouch with all my software, my micro-mouse, my professional cards, my notes for the current project I'm working on and all of my backups of the project.
Then my gym bag:
My walking shoes, a small towel, lotion, deoderant, moisturizing spray (for my face), my sports watch, toothbrush/toothpaste and sometimes my flat iron. Why do I carry this around? Because with my job I'm not sure when or if I'll get the time to work out, so I carry it with me in case I can squeeze a 10 minute walk in or even a 30 minute workout during lunch.
WHEW... you asked!!! LOL
