I can be a very good packer. I can be a horrible packer as I discovered this summer on my 10 day trip to the UK and Germany. I ended up with a bag that was too small to fit stuff I had bought from shopping, a bag that was falling apart and then carrying a backpack that was too heavy and causing problems for my neck and shoulders/back.

Lesson learned. But it doesn't help the airport/railway stations charge a lot of money to store bags for 24 hours or more...it quickly becomes too expensive to store bags you wished you could. Instead of dragging everything around from hotel to hotel.

Ended up buying a new suit case which still turned out to be too small for all my stuff....so, I need to improve in this aspect of planning.
