Students should know that life is too short to do a course that they don't like doing. They have to make sure that they are doing the things that they love doing so that they can enjoy living their life. They should change their mind and decide that they will do what they have to do to reach their goals. They only get to live once and opportunity also comes once. Let them embrace it when there's time.
People who know that won't waste their time and they will always pursue their passion. They won't mind the work that they will be doing as they are chasing their dreams. Some of these goals or dreams might take a long time to achieve, but these people should never give up because the time will pass anyway...
