Someone may have all the technical knowledge, scientific intellect and business know-how but when he/she decides to choose laziness, excuses, procrastination, complaining and other bad attitudes, his/her relevance is meaningless.
Make your education valuable. Apply what you learnt. Refuse to take the back seat and watch things happen. Join the change and be part of the change.
Education is not merely meant for you to write and pass exams, get a good job and a good spouse, and settle down for survival.
