When I buy something, be it, a plough, lorry, fishing rod, car, kilt, or anything else apart from day to day shopping, I have two things that I always ask myself.

1.The most expensive thing you(me) will ever buy, is something you really don't want.So do I really want it?
2.I must divorce need from necessity. In other words, I may need it, but is it really necessary?

Do I always get it right? No way, but it helps!
