Start with wishful thinking

In other words, start with the end result. Whether it usually involves something like wanting to create a 2.5D fighting game rivalling Arc System Works, a gorgeous anime-inspired illustration, a flashy short animation, or a cool-looking demoscene.

This is also the core of prototyping, starting with the end product and getting there no matter how badly implemented.

In Programming, we usually call this abstractions where we don't need to worry about the implementation details and whatnot. Some would even take one more step by starting with the user-oriented documentation or unit tests.
In Skill-building, we could start with our end-goal dreaming about the completed project. This is quite similar to Thomas Frank's impossible list that we explicitly say what we want to do. We could apply the principle what we want to do when we learn a skill.

However, focusing too much on the destination can block your progress from having a clear sight on how to get there. It could be just the endgoal is tad more difficult. Diving head-first into a difficult problem makes a bad start. We can Create roadmaps to stay on track and establish milestones.

All of this allows to iterate through the project multiple times as Consistency over time creates more progress.
