Two great posts that are worth your time.

1. Hand-Written Notes Have Become A Power Tool by John Jantsch at Duct Tape Marketing

2. The Power of a Note by Dave Lorenzo

Both talk about the power of hand-written notes. I have to agree with
both John and Dave and endorse what they say fully. Both John and Dave
give you a ton of reasons why you should write and not type. Let me add
one more reason to their list:

** It’s hard to multi-task when you
write. If you care enough for someone it is worth focusing fully on the
writing the message (it takes only a few minutes) **

Enjoy!
