I don't agree. I see everything in relation to all my costs and all my profits.
If this 1K would represent 2% of the total amount of paid commissions I would do nothing. Because you can probably save 2% on everything you do in life. Watch your list of things that improve your net income and take the most important savings (in percentages!) first.
If you would make 50K a day it might be better to focus on trying to increase your profits by 0.1% which would be roughly 12K instead of saving 1K in commissions.
If people would not watch their savings in percentages, all billionaires should be trying all day to save money on food, cars, cloths, holidays, hobbies... In short they would have no time anymore to enjoy life. They would be busy to save small money, small money that they even don't need to have a good life. Why waste your time on something that has no importance at all in life? Spent this time on your family and friends.
