The main bottleneck to learning new skills is access to good feedback from experts or coaches, not time.
When I first started teaching myself programming I wasted ages on pointless things that didn't get me anywhere.
Makes me wonder if there would be value in a cheaper form of university where instead of going through the whole process you just get access to experts you can talk to and ask your dumb questions.
I know there are a lot of places on the internet where you can ask questions but they tend to cater to experts only because most people don't like answering beginner questions that get asked 100 times unless they are paid to.
