I often wonder if it's the speed of the technology improvements or something else that makes us forget the old fashion pen and paper. Many times we fall into a trap of purchasing the latest or coolest software before deep understanding of our actual needs.
I've had clients ask me what was the best Task Management app. They were surprised when instead of listing a couple of apps I said "Go Low-Tech before you buy High-Tech!"
Use a pen and a piece of paper for a couple of weeks to track your to-do's, learn what you need and how you work. Once you understand your modus operandi, look for an app that will fit your task management style ... or you might realize that the low-tech solution is all you need.
