Driven to Develop

I seem to reach a point at which I feel a driving need to change tools. First it was from paper to My Life Organized; then it was MLO to MonkeyGTD; now it’s MonkeyGTD to something else. Why do I feel the need to reboot my system?? Is it a symptom of not keeping things “squeaky clean” or just “tool-itis”?? Obviously if I’m rebuilding my system on a regular basis, I’m not getting things done so how do I stop this madness??

I know that there’s a tipping point which I must pass in order to really “get” GTD and most folks say it’s just time in the system as a whole but I’m beginning to wonder if system hopping is the same as pressing a reset button for myself.
