Hi Raveesh,
You had asked a very basic and very important question. Many times it is seen that even after serving in HR for say 3-4 years, the person doesn't know why they opted for HR, and that is the time when the slow path begins in one's career.
The answer to this question is always different, but the best and most genuine one is the very beginning point of the career. It is not your first job or first project in HR. I am talking beyond that, when you choose to select a specialization. Yes, that is the point where the right answer lies. I will explain why.
A blank mind always produces the optimum result. So at the time of choosing the specialization, one is totally blank or you can say your mind is focusing on only one aspect. You ask several times, "Why HR? What is there in HR? What will be the probable future in HR?" and endless "whys."
The best part is, you answer all the "whys" at that time, but in layman's language. For example, "I like to interact with people." This is not wrong because none of the answers to this question could be wrong, as everyone has their own reasons and justifications as well.
Okay, coming back to the topic. So now you have the layman answer to this question. After that point of decision, you move on to studying the concepts of HR, then you practice the concepts. At this point, you and your mind are not in a condition to accept the layman answer to "Why HR?"
What you have to do is furnish that answer with proper terms you have studied to date and see whether they can be best utilized in the corporate world. This will increase your confidence as well.
Want to try this? I will help you.
Take a paper and pen. Put down the points (layman points). These are the traits as well as opportunities for you.
Now try to furnish them, take your time. Once done, just go through it as a professional (you are the best judge of yourself, that's why self-appraisal system is in use).
You will find not only the right answer to this question but also the right way to answer the question, "Why HR?"
You know, I had chosen HR for the above reason. This is my best side of work and personality.
Hope this will help you and others who will read this. Best of luck.
