Sometimes deviations from the execution of vision are necessary in achieving the vision. This is less a notion to allow one to procrastinate, and more so a stress on the need for rest and space. Most notably in creative pursuits where forcing the solution precedes a worse solution. Space from an obstacle, as in the act of affording a new perspective is highly useful in tackling it. This ‘space’ can come from doing something completely different, something as simple as going out and enjoying yourself, exercising, anything that promotes a lack of lethargy while being different. The brain works on problems in the background while doing other tasks, this is why inspiration strikes, and how solutions can just hit you in the shower. So, remember to take some space every so often, and get after that vision.
Meditate.
