2. Travelling keeps you content in the long-run
By travelling, you are not only just being happy and having fun for the time being. Its effects stay with you in the long-run. For example, you are meeting new people and making friends while travelling. You can still keep in touch with them after you come back to your hometown. Going to different new places help you gather knowledge, and experience many things in life. These experiences will never fade away from your life. You will eventually feel good cherishing your memories throughout your life.
