Packages can indeed be very useful, and this is good advice -- but in my 
experience at least, slightly incomplete:

1)  There's the BeginPackage[---]; Begin[ ]  stuff and the End[ ]; 
EndPackage[ ] stuff you're supposed to include -- I'm still not sure if 
you _must_ include those (documentation of packages is somewhat arcane); 
and

2)  You have to Save the package in the right place, and maybe in a 
folder with the right name to access it; and

3)  I still not clear about the complex ways in which creating and using 
a package can mess with scopes and contexts, nor whether, if you edit 
the .nb->.m package combo during a session, you have to restart a new 
session to get the edits properly recognized.

But, packages are still very useful, nonetheless . . .
