Self Improvement is self-growth. It is the practice of empowering oneself without relying on the assistance of others. It is synonymous with personal empowerment, and personal development.
Self-improvement helps enhance strengths. Some ways of self-improvement include simple tasks such as trying to be punctual or waking up early ... when you were never punctual and you are far from being an early bird.
As the saying goes: "Growth begins when we begin to accept our own weaknesses." So if you are fond of borrowing money ... tightening your belt is a step in the right direction.
Improvement begins with "I". And LIFE'S IMPROVEMENT begins with SELF-IMPROVEMENT.
