Much depends upon how you define "impact". In the last month I have:
1. Diagnosed a patient who others thought had some sort of leukemia / bone marrow failure with Anaplasma, he completely recovered.
2. Managed a guy with opioid use disorder admitted with MSSA septic joint and epidural abscess. All of his infections had basically been treated, now just on a long course of Abx. No one had addressed his pain and opioid problem, he was using all sorts of narcs. I switched him to methadone, which he was unwilling to consider with others but I sat with him every day, listened to his story, bonded with him. He trusted me, we switched him to methadone TID, and then moved him to single day dosing so that when he is finally discharged he can transition to a methadone clinic. He seems committed to staying off heroin. Will he? I don't know, but I think he has a chance.
3. Put my 94 yo patient whom I follow with home visits on hospice. I plan to be at his funeral and speak.
I'll trade your Google impact for just that any day, and that's just the last few weeks. I love going to work. I get to interact with fascinating people, manage complicated problems, work with skilled colleagues, and students.
Could I have made more money doing something else? Probably. Do I end up working a bunch of weekends? Yep, and it can be frustrating. Is some of what I do incredibly frustrating? Absolutely. Would I trade it for anything else? Absolutely not.
