As a Tinkerer, you are a master of tools and a hands-on explorer. Your core drive is to understand how things work, and you do that by getting your hands dirty. You trust your own experience far more than any instruction manual. Hobbies that are purely theoretical or lack a physical component will quickly lose your interest. You're at your best when you have a complex system in front of you—mechanical, electronic, or otherwise—that you can deconstruct, understand, and improve.
