You definitely need to put yourself on a self questioning chopping block.
It will not only affect your professional/academic/student life; but your personal and social life as well.
It can make you happy or sad, it can ruin your relationship with your partner, it can make you depressed or in extreme cases lead you to addictions or eating disorders…
However, it can be one of the greatest experiences of your life!!! It may drive your life into a heaven of self improvement, you might look at yourself in the mirror and say; “look at me, who could have predicted that I would achieve this???”
… And when you’re done, the reward is even bigger: “I did it” and then you will join the “club of people that create knowledge”
….But before you put yourself in such a rewarding and painful commitment, you HAVE to question yourself:
Why do I want to do this?
