... you are carrying all the same things.

If you leave something, like the logbook, or EFB, or helmet, inevidably you will find yourself sitting in in the acft ready to start with something missing, or taking off with something missing.   Better to have a flow...   ALWAYS carry out these things so you don't inadvertantly leave them behind, or have someone take them from your cockpit withtout your knowledge (like the logbook)
