You will not have enough tools until you have accumulated each of the following sets:
1. Inside your main working multi-bay, double decker with side wings, connected by a pintle hitch to a similar caboose: at least one of every tool ever invented for your specific trade. Brand mixing is OK, so long as only one brand is represented in each drawer.
2. A back-up set, as above, compressed into a single roll-away top/bottom. No need to include tools invented prior to 1940 if a modern version is on hand.
3. One traveling set to take along on family vacations so you can periodically demonstrate why you need so many tools.
4. One set of tools to lend to others: Cast iron ball pein hammer, K-mart adjustable wrench, AutoZone 6-in-1 screw/bit driver set, knock-off Channelock pliers.
4. One tool box / bag for each type of household project: plumbing , electrical, sprinklers, carpentry, drywall, masonry, HVAC.
5. A specially tailored set for your spouse that you will never be allowed to use. (Caution: no sharp objects).
6. A small set for each child in your house old enough to ride a bike.
7. A complete assortment of antique or vintage tools related to your trade to cover one whole wall in your living room.
8. Tools set aside as gifts for the special people in your life. Start out small. If you give them a tool and they don't respond with the same enthusiasm as they would have if you had given them grandma's diamond wedding ring or grandpa's gold pocket watch, then ****** to tool back and scratch them off your gift list.
9. A complete set of tools for each hobby. Don't overlook tool repair and restoration.
10. Whatever tools you might need to get yourself out of a jam.
