I can design almost any mechanism now, shave grams and cost off anything they hand me. But cleaning out my desk last week I found a notebook of ideas I never built, things that were mine. A whole career making other people's machines a little better, and I wonder what I ever made that was actually my own.
More people experience this than they realize.
You can perfect any machine, but you wonder if you built anything that was truly yours.
If this sounds familiar, the Library can help you find the bigger picture.
