Yeah, the mechanic profits off of me not knowing my engine, and I profit off of him not knowing his computer, and in the end we all get along.

The pharma co is taking advantage of me because I don't know enough chemistry to mix that stuff up at home? Their profits are through the roof!

At some point you have to concede that one man with one life can't know everything, and focus on learning what you care about.

You can be a jack of all trades and master of none, in other words.
