I have bought a lot of gear thinking it would help my progression. Maybe in some ways it did. But pretty minor percentages. I found I had to plan on flailing and failing to progress. I also have light and puffy winds where I sail and it seems like a hard won accomplishment to get on foil and cruise. Just mowing the lawn far enough to let my heart rate come back down seems necessary. When I scheduled ten foot swap attempts per session is when it came together. The wipeouts were budgeted and acceptable. More than ten and you're just beating a dead horse. Your senses, thoughts, and body come together and are more effective than cool new stuff.
That being said cool new stuff is being delivered on Monday.
