I am a lazy learner

I used to write with only what I have already known already knew, I never thought about forcing myself to use advanced words, which is important

I am so impressed to see there are so many language learners above 30 or maybe 40 years old.

I thought age is vital essential, its actually not, your will is.

"vital" normally collocates with a "to". It's more common in formal writing, much less in informal

"Regular study is vital to language learning"
