I want this and I need this are two different things most people don't yet understand. Wants is for immediate satisfaction, why needs is for the long term. If you keep wanting you might end loosing so many things in your life because they won't last. Needs might not seem good at the moment but will really help you in the long term.
You don't have a business or a constant source of income but you are thinking of buying the latest Iphone 14 which is a very big want, why not use that money to invest in a business that will give you a long term profit, instead of chasing something that will not last. That phone will come and go, new ones will be produced so where would you get the money to get new ones when you did not invest in the long-term.
Controling yourself from wants is always hard, but we all later agree that those wants that we were craving for was not worth it. A rich man once said if you want to be wealthy buy luxury(wants) last, but if you want to be poor buy luxury first. This explains it all. Never choose wants first, always look out for your needs.
Thank you.
