I can design a machine that hits every target no matter how tight the limits. Thirty years of making other people's systems run better and faster. But last week I sat in my garage and realized I've never built one thing that was just mine, and I don't know if all that optimizing added up to anything I can call my own.
More people experience this than they realize.
You can make any machine perform, but you wonder if a career optimizing them built anything of your own.
If this sounds familiar, the Library can help you find the bigger picture.
