If you have the funds for a car get it. The problem is peoples idea of a car. A car is necessary if can afford it as an adult. It can help you save time getting from one place to another and also make your life easier. What are you making money for if you can’t at least make your stress simple. You don’t need to own a luxury car just one that is neat and comfortable.
If you don’t have the money to get a car or a house then I understand you but if you can comfortably get one but see it as a bad move you need to have a rethink.
This must be based on the needs that exist within us, not just style or prestige, such things are only needed by the ego, not the whole personality, wealth or success does not describe anything if it is difficult to achieve it, but as long as we can fulfill the needs of life and have a comfortable life without the demands of ego and prestige, that is already a successful and rich life without abundant wealth.
