Rule #20: Ask for opinions

Unwritten Rule of Engineering #20: Cultivate the habit of seeking other people’s opinions and recommendations.

You cannot hope to know all you must about your field and your employer’s business. Therefore, you must ask for help from others; routinely seek out those who are “in the know.”

This cannot be emphasized enough and is an especially frequent flaw in newer engineers who believe they know everything. Typically they do not understand the larger context and thus make locally optimal but globally sub-optimal decisions; decisions that could have been avoided if they had asked for advice from others.
