There is no greater harm than that of time wasted.

…And don’t worry about perfection, just keep moving. Certainly, you will need to make adjustments along the way to your destination, but dedicate a specific small block of time each week—perhaps an hour over the weekend—to check your bearings. The remainder of the time, remain focused and keep moving forward.
The true measure of your success will come when you meet your next obstacle (of many), and you continue to move forward in a focused manner despite the roadblock.
