Absolutely doable. I support most recommendations - here's my two cents:

Comprehension is the thing. You learn a language by understanding messages in that language, and nothing else. (That's the gist of current language acquisition theory, not just some hearsay.)

This implies: Make sure that you focus on stuff that you like and that you understand. If you need to do too much looking up, find something else. As long as you're B1, that excludes a lot (but not all) of authentic sources like TV, movies, even newspapers or Slow German. Those limitations will not last long though.

Don't wast time on "grammar", "drills" and "practice" or systematic vocab learning. If you like, buy yourself a grammar reference, not a practice book. When you've discovered things that need clarification, look them up. You'll see that this doesn't take long.

For now, DaZPod, a podcast specifically for German learners, could be an ideal source for you.

On speaking/communication: Simply try not to speak English/Spanish. At all. If that's too hard, set aside certain times during which you communicate in German only.

I can't tell you a lot that will actually help you, because I am not very familiar with studying German because, well, I'm a native. I am just here to tell you that I highly recommend NOT using r/ich_iel for the purpose of learning German in any way, because it's a running gag there to translate things from the English language word for word, disregarding German grammar. You could end up learning something completely wrong. Also, good luck. You have a tall task in front of you. It's hard, but I think it's possible. More on reddit.com

It is my belief that the pickup truck market is actually the hardest one to break into. Why? There's a number of reasons: Ford, Chevy, GMC, and Ram sell so many trucks, they are able to drive production and component costs really, really low, thus they can sell for cheaper and offer more options The super high volumes allows them to amortize fixed costs (engineering, design, tooling, etc) very thin. Thus they can sell these trucks for cheaper and offer more options There's a strong network effect, customers have strong brand loyalty, and fleets (who buy like, what, a quarter to a third of all trucks?) try to minimize the number of brands for easy service The German brands lack dealers in rural areas, where trucks are the most popular.

Here’s the reason they gave, which sounds familiar from an American perspective, too: “Sixty-four percent of parents said there were not enough child care options in Germany. "We saw fairly clearly that the more child care possibilities the parents have, the less they regret having a child," Geissler said. Professional fulfillment was another important issue. Forty-four percent of mothers and 20 percent of the fathers said they would have done better in their careers if they hadn't had children.” More on reddit.com
