Focus on progression in life, not perfection.
Perfection is an unobtainable goal. Everyone can achieve progression. Life is about the journey, not the destination. If you focus on a point that is always just out of reach you will have created a perpetual state of failure for yourself. But if you focus on progression you will live in state of success.
Goals are important because they create the movement and purpose necessary for a happy and healthy life. But be sure to reward yourself by celebrating the small wins as they occur because this positive self reinforcement will turn into consistency and consistency is the true driver of lasting success.
