Yes! The guilt eats you alive and completely paralyzes you! I never could figure out what made me tick to help improve my study habits. But I just graduated so I managed and now I’m done forever! You will always wish you started sooner, no matter how early you start.
For little things like emails, consider how they take barely 5 mins to do. We have 1,440 minutes in a day and we can’t even take 5 to send the freaking email?! I use that mindset for chores too. I gripe and moan about the kitty litter box but it takes 60 seconds to just scoop the damn thing.
