Vision does not create results.
Goals and planning do not create results.
Only action creates results.
Any action towards your goals and vision is better than all the planning in the world and no action.
How do you know your detailed plan is right? If you are heading down a new path planning out all the details in advance is treacherous. Things change and you spend all your time adapting your plan rather than taking action.
So have a vision, do "enough" planning and start taking action towards your goals. Avoid analysis paralysis. Be open to different paths along the way.
After all, actions speak louder than words.
