As far as I can see it, I've the capacity to jump in feet first and screw up, but hopefully I've the capacity to undo stuff too. When I was a kid I once took apart the family's waste disposal unit from the sink. It was broken, but my attempts to fix it ended up in a total rebuild as I foolishly caused more and more of it to come to pieces in my hands. I believe it's still working now after I stayed up that night piecing it back together. Admittedly I put one bit on a bit wrong, but you can't have everything. I was totally engaged and at risk then and it was great.
Better get back onto it.
