<prompt> Human: Hi everyone,I was promoted to the partnership of my big law firm in May, and I have been thinking about buying myself a very expensive watch to reward myself.How would you go about defining a budget for that? From a financial planning perspective, it makes little sense as it is money I will never get back which, as a naturally frugal person, is a big thing. At the same time, I have just achieved a life goal and feel like it is worth marking in some way.If you have been in a similar situation, I would love to hear about your experience.  <response>: I was sorely tempted to buy an Audi TT when it first came out. Instead of making that big discretionary purchase, I made this smaller discretionary purchase instead. Every time I look at it I smile a little, because Im glad I avoided what I later consider would have been a mistake.
