Haha, although I don't have a way to solve your procrastination issue in a day I do on the other hand a little tip to help your packing for coming travels!
Step 1: As your pack your bag going somewhere (e.g. 2 weeks, warm location), make a list in your fav' note-taking system with todo checkboxes next to them
Step 2: The next time you go to a similar location, surrender to your nature and wait to the last minute then throw everything on your list down while checking things off
Step 3: Uncheck the boxes before next trip and extend your system with different lists such as "Weekend", "Three week work location", "Ski vacation" and repeat!
Otherwise, if you're into travelling, vlogs, self-development etc feel free to check out my channel, in any case keep up the good work and I'll see you around! 😄
