It is not true that everyone thinks this way. Many people strive for success without "breaking bricks" first, as you say. However, that is usually a bit harder.
The "suffering aspect" does not have to be true for a person to achieve success, but it's better to develop patience and calmness, and not overreact, like a child, when faced with various situations , even if they're difficult.
Beyond "being a millionaire", what is success to you?
To me, success is to be happy. Having found a meaning in life, a meaning to which one is completely invested in, one could then achieve success with determination.
Must one necessarily suffer before he/she could be successful in life?
Although, the answer may be no. The truth is that in some cases, one may need to work hard to achieve success. However, I would not say that they should become slaves to their career just to get success. Rather, one must do what he/she wants to do.
