Hey, learning is good!  Be glad you don't know everything!  ;^)

Certainly save all you want when playing around.

The development style is to create a package for code which specifies 
any other packages it requires.  Save your package as you go along with 
code as you write it.  Don't save the image.

The next day, just "Feature require: 'YourPackage'", and you know at the 
end of this process, anyone else can git clone your package repo and be 
able to "Feature require: 'YourPackage'" and have all requirements met.  
No one is in "library hell" trying to figure out requirements and 
versioning.  It just works (or complains about a missing requirement).

One learns to think compositionally.  You can learn the base five to six 
hundred classes, then you only need to learn each package 'delta' to 
understand what is added.  So one can learn by composition.

The sample package tutorial in 
https://github.com/Cuis-Smalltalk/Learning-Cuis is pretty quick:
