I fully agree that consistency is the key to achievements. But it requires will power and discipline of very high level. After working 5 or 6 days in a week, every one wants to lay down and pass time leisurely in viewing TV or chit chatting or just idling but there are people who engage themselves in creative activities like gardening, social work, academic work, manual work in the house and many such things which are actually falling in the positive territories. These are the people, I would say, who are consistent in their approach to life. Wasting time is very common but if one does that then he is losing a great opportunity which would never come back in the same slot. It is gone for ever.
Knowledge is power.
