This. I'm an electrical engineer and took the time to learn many of the fundamentals in my particular corner of the field. I constantly recommend others to do the same as it means you can do any analysis or study far easier. It's not just learning existing engineering software packages either. Once you know a little programming, Excel, or SQL, you can even build your own tools from scratch when the vendor applications don't do what you need. I've often found that my company has done something one way for years that is inefficient, slow, and less accurate than a process I can setup in a day or two. This all comes from the fundamentals. Learning these fundamentals isn't easy though.
