What productivity hacks/tips/tools can you all share as makers? Let's start a helpful thread

I always strive to find new ways to be more productive, and my biggest game-changers have been: 1. Always have a to-do list and focus on 1 task at a time (multi-tasking decreases productivity by 40%) 2. Never book meetings back-to-back 3. Use Pomodoro timer - 45min work 15min break or reward (can double these up if I am feeling the zone) 4. Block apps and browsers in working hours 5. Use Notion and Calendar for setting reminders
