When you start a project, you focus on execution and that's normal. But what if planning was what you liked most?
Save yourself the hassle of execution and concentrate on the business plan side of things. Test your business plan on Business Ideas and work on it until it reaches a good mark.
Then all you have to do is to delegate the execution to others and move on to the next project! Do not hesitate to use this technique for your own business plans as well as for others.
