Is it normal for stimulants to help focus but not motivation?

Yes. Medication can improve the ability to sustain attention once you start, but initiation is a separate executive function. Starting still requires activation energy. Many people notice that once they begin, medication helps them stay on track. But the first step can still feel heavy. Using external cues, countdowns, body doubling, or committing to just five minutes can bridge that gap. Medication supports the engine, but you still turn the key.
