moral of the lesson, dont hope or expect that what you learnt in school must pay. most rich people today didn't achieve success from what they studied in school but what they could offer after graduating. dont despise the days of your little beginning.
The process of life that we live does not always run smoothly and sometimes there are times when we will get problems to mature us to live life. School does not guarantee someone to be rich but school is considered quite important as a basis for understanding knowledge. To achieve wealth you need to see opportunities and other supporting factors and even people who do not go to school or who go to school will achieve wealth if they understand what needs to be done.
Starting from the bottom is a much more enjoyable process and maybe the concept is like people building a small business first so that they can slowly develop the business into a bigger one. People who start from the bottom usually understand the difficulty of the process they go through so they will fight harder to achieve success.
