You should structure your mornings and evenings strictly to make sure you don’t fail at these critical times. Your entrances and your exits are the most impactful. The starts and ends of the day are the most important as well. They set the tone not only for the day to come, but also for the day that has passed.
Be early to rise and complete the most necessary work of your day when your mind is the freshest. At the end of the day, develop a routine and stick to it, something that not only gets you ready to rest but also gets you ready to wake up in the morning.
This must be mandatory. Every time you try to improvise a great start, you fail. Your will alone is too weak to decide you will make use of the hours of the day. Your mind and reason must also come into play and assist your will in making it happen.
