Brian Tracy identifies 5 main reasons why most people do not become wealthy:
1. They do not realize that becoming wealthy is possible for them since they lack wealthy role models.
2. They never make a firm decision to become wealthy and take the necessary steps.
3. They procrastinate and always find reasons to put off taking steps towards wealth.
4. They are unable to delay gratification and discipline themselves to save money instead of spending it.
5. They have a short-term perspective and do not consider how their actions will impact their future financial situation.
