You should strive to create habits in the way in which you want to be. Make a habit to think and evaluate more; effectively putting your conscious mind into gear before reacting to life.
Everything you do, you should do thoroughly, and to the best of your ability. No matter what you do in life, be proud of what you are and what you do. Always aim to be that person of warmth and kindness with a sense of happiness and humour within you at all times.
