It is a lot faster learning a foreign language when putting ourselves in situations where we are forced to converse in that language, than when we are merely learning it on Duolingo or by listening to audio lessons.

It is a lot faster learning how to drive by actually going out on the road than when we are merely driving with an instructor who has access to brakes and the wheel.

It is a lot faster learning to code while trying to create a program with a real world application than when we are following the lessons in a text book.

We learn faster by forcing ourselves to actually do the thing that we intend to with what we have learnt.

So, start doing.
