I unfortunately relate. It's incredibly tough and I struggle with it every day. I work in polling and regularly pull 12+ hour days + weekends. What works for me is doing a few 5 star questions whenever I have a couple free minutes, heck even in the bathroom at work (don't judge). And since we don't have the luxury of quantity, quality matters so much more. Really dig into each question you got wrong, + scour for patterns in your wrong answer journal. And lastly, it's easier said than done but try not to beat yourself up about it. You are doing the damn thing!
