I started learn linear algebra and some mid-level math stuff couple of years back. While I really wanted to learn I still struggled to find a good learning path and use a product similar to Duolingo for math.

Eventually I learned some, then stopped using it and then forgotten all of it.

But my point is despite if me really want to learn I found it quite challenging to find learning path that I trusted to be good start for me.

I also need to make the point; I didn’t have 5 hours a day, so this 30-90 minutes in a good day endeavor.

There are still tons of things to solve in this area, how to cross to chasm, a learning path that’s right for you and how can you be sure of that. Learning something in one good 60m instead of 5 different videos and 5 hours. Etc. I think these problems are far from solved.

I also want to get fit but that doesn’t mean I’ll show up in my gym to workout everyday. So even when you really really want to learn you still need to stay motivated.

For that 3Blue1Brown is very good for this.

Better Explained as well, but focuses more on how to understand the concept so you can start to learn.

What you're looking for is not something to help your with your goals, it's something that sells you the idea that you can achieve your goals while seemingly be unwilling to put the necessary effort in.

What if it's simply impossible to learn linear algebra and mid-level math stuff by spending only 30 minutes a day? What if you can't get fit if you don't go to the gym?
