Start a daily note of what you learn, it helps more than you think
When I was first learning tech stuff, I used to forget things almost as fast as I learned them. What really helped me was keeping a simple note on my phone where I wrote down one thing I learned each day. It could be a keyboard shortcut, a command, or just something I didn't understand before. Even one line is enough. You can use the notes app that already comes with your phone, no need for fancy apps. I still do this today. When I'm stuck on something, I quickly search my old notes and it saves me a lot of time. Try it this week. Every evening, write down one thing you learned about tech. After a month you'll be surprised how much you actually know.
