Most stalled projects were not too hard. They were too big to finish in one sitting, so they never felt finished. A win is something you can point to and say: that is done.
Pick the smallest version of the thing you want. Not the launch, but the first page. Not the system, but the first automated reply. If it fits in a week, it is the right size.
Finish it fully before starting the next one. Done work gives you information, confidence, and something to build on. Half-done work gives you a longer to-do list.
Then repeat. One win at a time is not a slogan about going slowly. It is how small, practical steps stack into larger opportunities.
