Summertime and the living is… frustrating

So I have all kinds of extra time this summer, and have been alternating between Photoshop tutorials and learning how to use a cricut explore air 2. Is it possible that I am really too old to learn, because it’s all just getting me a little crazy. As I learn the advanced photoshop techniques, it seems that my granddaughter can do the same thing by just using an instant app on her phone. Am I wasting time?
