The Twenty One Day Rule

We are entering a period of time when you could be hurting your bottom line in both ways. From a financial perspective, bottom line is the net profit or loss after all expenses.

When I say you could be hurting your bottom line in both ways, I was implying (a) impulse buying / holiday spending and (b) the feasting that would result in an increase in your body weight.




Here is something that I follow religiously before making any major purchases. I pause and ponder about it over a three week period and I ask myself repeatedly,

  • “Do I need it?”
  • “Do I really need it?”
  • “What is the use case for what I am about to buy?”
  • “Can I get by without it?”
  • “Is there anything that I already have able substitute for what I am planning to buy?”


As as I pause and ponder over the questions above, I read product reviews about the product that I am interested in. At the end of week two, one of two things happen:

  • I have lost interest in the product or the product has poor reviews. – OR –
  • I am strongly convinced that I need the product and the product reviews are really good.


If I at the end of week two I am strongly convinced that I need the product, then I start looking for the lowest price at which I can buy it. At the end of week three, I place the order. I used to be a spendthrift. This discipline has saved me from several impulse buying decisions.


As turkey day approaches, here are a few words of wisdom:

  • Just because something is on sale you don’t need to buy it.
  • Having less things and more cash in your hands is just plain old common sense.
  • The best place for your money to be is in your wallet.

Spend wisely.
