People don't always have to know what you do for a living when they are able to tell you that you are doing well. People are able to develop a strong opinion about how someone is doing based on how they see them living. They can form a positive or negative opinion about the person based on what they see them doing with their life.
People are able to make an opinion about you when they know that you are doing well without knowing your source of income. For example, if you were to walk up to someone and say that you are a doctor, they would automatically think that you are rich and successful.
If you were to walk up to someone and say that you are a factory worker, they would automatically think that you are poor and struggling. The key is to have a good lifestyle that is not showy, but people will know it. This will help you to keep your image and your personal privacy, while still not being judged.
The impression of people when they know you are doing well without knowing your source of income is that you are wealthy. They will assume that you are wealthy because you are living a lifestyle that they are not able to live.
They may be surprised when you tell them that you are not wealthy mostly especially when they have the mindset that you are. My point however is people intend to derive a mindset of people that look so attractive and classify them as being wealthy meanwhile we don't judge a book by it cover.
We live in a world where we can't really say who is who base on appearance and this however is a personal lifestyle to choose where some people choose to live a simple lifestyle without showing off while we have majority that do so which all depends on choice.
The most important thing to take note is to never look down on anyone because we might not really know who they are and we just need to be careful with our actions for future purposes.
