You must have heard this quote in finance that “Don’t put all your eggs into one basket.” It simply means don’t invest all your money into one financial instrument. It sounds intuitive and yet many people around us manage their careers with a single-stock mindset. They fail to diversify their skill portfolio, and gradually they lose their attractiveness in the eye of a potential employer. 

It all comes down to their mindset. People who operate from scarcity mindset tend to have fewer skills in their arsenal and people who have abundance mindset have no problem putting themselves in the process of leaning. You need to have abundance mindset in order to diversify your skills because one calling is sort of a myth in this ever-changing world. In reality, life is a series of what works and what doesn’t.

You should not limit or restrict yourself just after graduation because we live in a time where your job could be replaced with a machine or a piece of software at the same time you should avoid spreading too thin and learn few skills thoroughly. There are endless possibilities in skill diversification so you need to make really smart trade off.
