if I may be honest I always spend all my salary to buy a certain item I like, yeah I'm very hard to control my desire to buy something, there is the suggestion that I was not too extravagant?
In the past this habit was just a wasting of my money for me and I preferred to save and invest in the future but now I realized that spending our money on our life is also beneficial and worthful to spend it on our family members as no one know about the future that will it be with us or not.
I wonder who is the salary enough to fully meet his family all necessary. It's fantastic. Although in different countries, different capabilities.
I haven't done that before to buy the things that I want, because that is a total waste of time and you won't be able to save some of it. The best thing to do is you need to think about the certain things that you need not the wants because if you will prioritize it then for sure you will be able to meet your expected savings when you are going to forget about your wants.
Some time you can ignore your wishes specially when you have limited amount and cannot afford to buy all the things you need, but when have a decent income then it will be too difficult to control your self from buying things you wish even the unnecessary things.
So you need a good strategy to control yourself from purchasing such unnecessary things that you do not really need and can save some money for your better future and for your decedents.
