Do You Feel Like You Can Work for Longer?

It's surprising how little time you have to dedicate to creative stuff. You're absolutely maxed, you have like 4 to 6 hours of really high intensity cognitive power and then it just slowly goes down throughout the day. I do feel that doing like interleaving multiple things like switching every like 20 minutes or whatever or setting when you do your reps if you like set it to like four items for every one topic or something. Do you feel like you can work for longer doing something like IR than you could doing like some equivalent just like reading? Yeah, you know I think so because with I don't really get bored or  because you're constantly seeing something new.
