The way you build momentum is by getting something done and then moving on to the next thing. No one likes to be stuck on an endless project with no finish line in sight. Being in the trenches for nine months and not having anything to show for it is a real buzzkill. Eventually it just burns you out. To keep your momentum and motivation up, get in the habit of accomplishing small victories along the way. Even a tiny improvement can give you a good jolt of momentum.
