Yep, let me summarize/amend a bit,

Prioritize - Identify what is most essential, then work down from there. Hydration is more important than food.

Fit to scale - Identify the scalar needs for each mode of operation. EDC is not the same as BOB.

Multitask - Identify equipment, material, and supplies that can meet more than one requirement. Candles make light and heat.

Skills - Focus more on how to improvise, increasing your knowledgebase, thinking outside the box. The more you can make use of what is readily available, the less you will need to keep with you constantly.
