Make your personal development plan simple. Put it in something that will allow you to carry it wherever you go. Post it in places where you can see it naturally. And when you make a scorecard, make it easy to understand.
Most personal development plans overwhelm people. However, I know of many performance gurus who sell personal development plan notebooks, planners, and job aids that seem to make a very detailed plan.
You can have a one-page personal development plan. For example, I use the 4 Disciplines of Execution in writing my PDP.
You may not be able to include everything in your plan. You don’t have to. It is not a feasibility study. It is like a Business Model Canvas. You can change it at any time to make it more desirable, viable, and useful.
