This is very relatable to me. Since you’re using the past tense, would you be happy to share what helped you get out of that mindset?
Still working on it! I'd say the biggie was finding myself at a not-quite-FAANG-tier SV company where suddenly I'm surrounded by people who are all amazing. Where you have to prove your accomplishments to get promoted rather than just being handed promotions because you're "good at your job". Some mentorship. Some reading. Being encouraged to look farther down the road (which implies it's okay to not 'get things done' between standups). Honestly, lots of self-reflection and looking around. FWIW I'd say I have about 25 years in the industry, so, it didn't come to me quickly or early.
But the problem was, I never considered my own growth. It never felt like a good use of time to take on more challenging projects because I wouldn't get the same sense of accomplishment. It would be hard, I wouldn't have much to show for myself for a few weeks, and so on.
Obviously this is all subconscious, you don't realize you're choosing things you're good at, or an expert on. Expertise feels nice! And, to be fair, not everyone's employers give them the freedom to choose/learn/grow that many of us enjoy.
