As I move through life I keep coming up to things that I don’t know. Sometimes those things are a bit formidable — like being tossed into the deep end with different technologies at work. Other times it’s just figuring how to do something better with my photography. Hell, I’m still learning how to better focus my Leica with the 90mm lens as strange as that may sound.
I’m still working my way through the Art of Electronics as well. I think the hard parts are behind me… the hard parts — the pages that take me a few minutes each to even start digesting the information — while they are frustrating they are also the parts that I love.
Those are the moments that you’re learning.
If you’re only doing things that are comfortable you’ll never get much better than before. Sure, you make progress a bit, but you’ll likely never make a step to the next level.
