I have observed that if you increase your needs, the new 'increased need state' becomes your new norm after a while. For example, if you didn't have car before but then you purchase it, use it regularly and then when you don't have it anymore — you'll miss your car, you'll feel like you can't live without it even though you managed to live without it before.
Do you agree with this observation? Would you agree that it's better to not increase your needs in first place?
In life, you don't remain the same; you grow, and by the time you grow past where you used to be, it will be a stage where you won't find it comfortable to come back. It doesn't even make sense to remain the same in life, let alone talk about going back to a previous stage. If we look at this in terms of financial state, it is very easy to manage the amount of money you have now, but if more money comes in, it means the demands increase. If one fails to improve their financial life and falls back to the financial state where they used to be, it typically seems difficult because there are already more demands.
There is a real difference when you have never had a particular thing before and have not felt how satisfying it is to own it. Once your want transforms into "a have", in subsequent times, that "have" will become a necessity and a need you begin to make provisions for. The more of our wants we satisfy, they over time become our basic needs that we can't do without and we cannot stop ourselves from satisfying those wants when we can afford it. We all have desires.
Same apply to rich people when they suddenly go bankrupt. They can never adapt to life the way poor people do. Many may end in depression for not being able to afford their basic needs.
