I was always afraid of long online courses - you start with enthusiasm, and after a couple of days you quit.
micro learning apps has become the opposite of such courses for me. There are no marathons or “get it done in a week” here, everything is according to your rules. I started with one topic — then I didn’t notice how I got hooked. I downloaded the app first just to look at the interface, and now it’s part of my daily ritual. I’m especially pleased that there is no boring theory — everything is presented through stories, metaphors, and real examples. You learn as if by the way, but the information is remembered surprisingly well. I was recently at a meeting, the conversation turned to neural networks — I was able to support the topic because I read about it in Nerdish. This really gives you confidence — you know a little more than yesterday. And this knowledge comes without stress. Small steps, but a big result.
