I first learn it fixing military jets, applied it to electronics, then tech, then my truck and car, then my motorcycle, my house, my A/C, etc etc. Properly learned, you can apply those skills to damned near anything. And as you apply them to more things you pare down what is and isn't needed, and become more of a master of said skills.
