As a beginner starting later in life compared to when I went to collage and started my day job I feel like I am forgetting things faster than I am learning them, and just curious if it is the same for other hobbyist out there that don't do this everyday for a living.
what I mean by this is things I have learned earlier in the year, practiced, understood, etc I feel like I now only have a loose understanding of. For example I learned how to use an micro controller, shift register, Hitachi chipset lcd, wrote all of the code from scratch to make it all work. Today I was looking back at it and I largely don't remember how I did it, but i suppose that if I had to do it a second time I could "figure it out" faster than I did the first time.
Another example, I went through and learned about various transistor amplifier configurations and biasing techniques and I feel / know I would have to open a book for sure to refresh my memory if i were to use it in application.
Maybe this is just normal? learn a concept, largely forget the details over time, but knowing the concept allows you to pick it back up when its needed in a project?
