Most people start their careers with stars in their eyes and myriad goals in their mind. These goals span a spectrum of needs and time horizons and could include something as immediate as buying an iPhone to something as long-term as buying a home for your parents.

However, instead of learning from your own mistakes, you can learn from those already made by others.
