Trust The Mind...
You can mull things over until they are polished smooth.
You can write, and re-write, your strategy and mission statement until they are letter-perfect.
You can visualise your plan, you can colour-code the tasks, and you can create the world’s best spreadsheet of actions, responsibilities and dependencies.
But at some point you have to get started and do the work, and trust that the mind that came up with the ideas in the first place is the same one that will work out how to get them done…
