The hardest part is being consistent and acrually using it. I have seen someone less tha. 80 IQ speaking their native language and understand the grammar better than someone with Havard degree both fluency in speaking and expressing their thoughts. The main reason is one have to use it day in day out, the other learn it as "subject" to past exam. Why so many people use babbel and resulted in not able to use the language. Spend 15mins, while native speakers spent 12hrs a day. Polyglots also use this forced immersion. Except they dont want to "brag" they learn that way. Instead just want to show how easy they learn ... naturally.

The trick is rather to make consistency easy. My own strategy there is aligned with most language enthusiasts: Make your input and conversations engaging! Make them so engaging you partake in those activities independently of the language, or better yet, in spite of the language. Make engagement automatic!
As an example, I've come to adore the French YT channel "ScienceEtonnante", and now watch anything published by it ASAP. I started watching it because I have a masters in physics, and found much of the jargon very easy to pick up as it's often similar to English. That left only the particularities of French itself for my brian to figure out. Now that I can simply lean back and enjoy the show, that is also what I do! It has become my favorite YT channel.
