I use to do this in school and tbh, should try going back. It was very much adapted from Cal Newport's method. Every morning I wrote all my to-dos on a index card from my Google Calendar. Anything that came up during my day which I could not finish within 5-20 minutes was written on the back to add to my calendar. This way I can focus on finishing the front side of the card and mindful of activities in the back. Now it's easier with the Things app (especially since I can email or have a script to send my todos to it directly). Highly recommend it!
