The barista who becomes the trainer, then the manager, then the roaster didn’t just climb. They kept learning sideways.

Advancement gets described as a ladder when it behaves more like widening. Each of those roles is a different skill rather than a higher version of the last: teaching, then scheduling, then a craft with chemistry in it. People who keep moving are generally the ones willing to be a beginner again at every step. Climbing is mostly a side effect of collecting neighbouring abilities.

Look at the job beside yours rather than the one above it and learn a piece of it. The ordering, the training, the machine nobody can fix. Sideways knowledge is what makes the upward move possible later.
