1. No more forced, stilted small talk with anyone at any time.
2. More proving your friends wrong to rub it in their faces.
3. No more being late (unexpectedly)...
4. Fewer forgotten anniversaries, meaning fewer nights of sleeping on the couch.
5. Better note-taking.
Type yourself notes and emails, or set alarms to give yourself reminders. It's a great alternative to writing all over your hands and suffering ink poisoning.
