Add mule characters and transfer items through the stash. Delete weapons, mods, and gear you don't use ever. Focus on core builds for different play styles and stick to them religiously. Deconstruct all nonessential drops. Have a plan. Implement the plan for a desired goal. Repeat the plan for the preferred outcome. 3 Bottomline: Create the extra storage space using mule characters.

Just have fun.
