Waiting on a package to arrive when ordering online can be awful. It seems like it will take forever to get a package from an online order but it will arrive sooner than you expect and then the time will speed back up once you get the package.
When waiting on a package try not to think about the package. Try doing other hobbies or do other things to take your mind off the package.
Try watching youtube videos, you can kill a lot of time watching youtube, browse the internet and look up things even if you know about them. Sometimes you can learn even more about something.
Take a walk outside, go walking outside, or go ride your bike. Take up gardening.
There's lots of things you can do while waiting for a package to arrive.
