The best way to get unstuck
Don't wait for the right answer and the golden path to present themselves.
This is precisely why you're stuck. Starting without seeing the end is difficult, so we often wait until we see the end, scanning relentlessly for the right way, the best way and the perfect way.
The way to get unstuck is to start down the wrong path, right now.
Step by step, page by page, interaction by interaction. As you start moving, you can't help but improve, can't help but incrementally find yourself getting back toward your north star.
You might not end up with perfect, but it's significantly more valuable than being stuck.
Don't just start. Continue. Ship. Repeat.
