if you have it fine, if not don't worry about it, think of all possible circumstances where you would need it and for who you'll need it for. In most worst case scenarios you'd stay in your home, for safety and cover.
but if you had to leave, tornado, fire, flood, chemical spill you'd have to leave relatively fast (minutes) what will you need or what would be very useful.

For now just use what you have and slowly build it bro! I keep my stuff in separate plastic bags in a hiking pack. A duffel bag would work, travel sack, whatever you have and fits your stuff good.

I make it all up and test it, for weight and carry.
