Before you start off, try some introspection as homework. Do you believe in reinventing the wheel? Do you believe in adding technical debt? If your answer to those questions was yes, you probably need to skip this chapter altogether. In all other cases, you should use a framework. Frameworks are good and nice with you. They help. They save time. They save effort.

Let's move back to questions. What is a technical debt? It is the amount of money at stake by a company where the technological architecture has been designed in such a way that more effort or man hours (and thus money) will be required to maintain the system in future. What is reinventing the wheel? It is the process of putting in more effort to carry out a task that was already done in the past.

Will you please stop scratching your head? This isn't rocket science. The analogy with software engineering is quite simple. You probably spend time in coding petty tasks, such as user input validation and password validation...
