TAKE TINY STEPS OR FAIL!
Knowing exactly what you want to make can often be the largest barrier in your creative journey.
Work on little prototypes
Explore each tiny concept and eventually, start to put them together.
If you are too focused on the gap between what you envision and what you currently have, you will likely lose faith.
Build on what you know
If you have a bunch of well-understood bite size pieces, it will make it much easier to combine them into bigger projects. But if you start in with building a big project, it is much more difficult to pull out the pieces you want to repurpose later.
