Setting principles for how you live your life will help you achieve your goals faster and easier. A life without plans and principles, is most times dependent on chances.
If all that are happening in your life, are things which happen only by chance, then you have submitted your will, time, intellect and energy to others. If you do not set principles on how you should live, you will definitely live by other people's principles.
Live a principled life. Have your daily, monthly and other periodic routines fixed. Build a strong character because this will determine your altitude in life.
