This holds true for everybody. It holds true for you. You cannot bring out the best in your without working very hard for it. In addition, you must be ready to do more than the things you like to do. Be ready to do the things you have to do whether you like to do them or not.
Many of the things that will take you to the top are challenging. They are not the things you usually like to do. More often than not, you will be tempted to skip them to do instead what you like to do. Skipping them is a sure way to fail to realize your dream.
For instance, idling is what many people like to do; but idling will not take you to where you like to go. Many people do not like to shun pleasures and work very hard. Yet, it is shunning pleasures and working very hard that will take you to where you want to go in this world. If you want to achieve your aim of becoming the person you want to be, you have to make up your mind to shun pleasures and work hard even though that is not what you like to do.
This means that to make sure you achieve your dream in life, resolve to do what you must do whether you like it or not. Why not take that resolution now?
