Very often, we are driven not by reasoned consumption, but by spontaneous desires or under the influence of external influence (advertising, "oh and she says that she bought herself this", "I also need it, I'm cool too," etc.). Oh yes, and also the desire to show oneself a "step higher", to create the appearance of wealth and prosperity
The first can be attributed to painful / obsessive states of uncontrolled consumption, the second to mental problems (complexes). How to deal with this? From a personal example - once in my youth, my wife and I constantly bought things for themselves. We rode around the world - bought, went to a nearby Shopping Center - bought things, saw online sales - bought things. Because we liked them, we could buy, we bought. Then it turned out that in the closet about 50% of the things that were not worn, and will not be worn. We did good and donated it to charities.
At some point, the thought came to me that it turns out that some of my earnings, and my wife, simply go nowhere. So I work, I strain - and this flies away to nowhere. I felt hurt. The conclusion was simple - either start to work less and earn to limit the budget, or ... I did not like the option to earn less
The solution was simple - we agreed with my wife, if I liked the thing and just "itching" to buy - then we go to the "cut" and the "adapted" theory of Sakichi Toyoda's "five why". It is called "3 Why". If after 3 answers to yourself you still have a reasoned position why to buy - well, ok, buy. And if not, this amount was transferred to our general dedicated savings card. After a year of experimenting, we had a moderately full closet, and more than enough money to spend a few weeks at a fancy resort, without too much limitation! As a result, it turned out that you can reasonably buy, not throw away unnecessary or not litter the space around you, while forming a kind of financial cushion that used to turn into air!
PS Yes, but this does not mean limiting yourself in everything, saving all income and living on one bread and water! This is another road to nowhere. Often, such people do not have time to use their savings, as they do not have time to live efficiently and fully.
