You may sometimes feel that you or the people around you are no longer the same. You may start feeling bad about it and wonder if something is wrong with you. But, let me assure you that it's pretty normal and alright. You can't stay the same forever. Change is inevitable and important. When making transitions from school to college or college to job, you would be required to make adjustments. You can't avoid that. We all are familiar with Darwin's theory but still feel afraid of accepting it.
Can you imagine getting to a destination miles away, just by standing in the same place? No! The same is with life.
If you want to reach your goal, you've got to progress, and for that, you need to change.
