One of the things my wife wanted to do was speak Spanish. She grew up in New Brunswick which is a French/English bilingual province so she had some multi-language brain cells from childhood (I think that's a real thing). Anyway, she started Spanish lessons in 2017 with a plan to be functional by fall 2019 when we had planned a trip to Spain. She was very functional by the time we went there and it allowed us the freedom to travel Spain with our own agenda with zero concerns about communicating. She continued with Spanish classes since then, and lots of hours on Duolingo, and is still at it. Fast forward to today and she is fully fluent. She says that she crossed the bridge to where she can think in Spanish in a conversation rather than translating in her head to and from English. People she talks to in Spanish tell her that they can't pinpoint her accent to know where she is from (she is a blue eyed blond so that probably confuses them too). Its amazing what she has been able to do to fulfill a key bucket list. I am so proud of her. And the side benefit of having a translator when we travel is pretty cool too.
