5S

Create Tidyness.  Throw away all unused stuff.  File away the rest.

Keep everything at the right place.  Keep the tools you need accessable.  Hide materials you don’t use regularly.

Keep your space clean.  Remove all traces of previous task before beginning.

Develop a personal sense of organizing your things.  Develop routines, optimize according to your needs.

Stay disciplined doing the above.  Make it habit and permanent practice.
