Easy: be poor. You will still lust after every new shiny trinket but you will be too poor to buy them.

Better, commit a large amount of your income to pension. Youll be poor now but rich later.

Or get a house you can barely afford.

Or have kids

[J_Darnley]

Wrong. All of those require wealth first. That wealth will be spent on shiny trinkets before pension, house, or children.

[bbcbasic]

That is simply not true. They require a job, sure. Anyone who can afford a new phone could at least with no credit rating or savings divert their pre tax salary into pension such that their net take home is small enough that they ain't buying tat.

You don't generally have to spend money to have children (once you have children, they will create new demands on your money.)

Pretty much. You learn to look, but not lust.

Or go for thing with more than just numerical increases.
