Personal growth is the ability of an individual to learn from himself in all aspects: thoughts, emotions, feelings, sensations, etc. Then that learning is applied in the challenges that life proposes to him.
Each of us has an inner strength that allows us to move forward in any circumstance. That strength is based on self-knowledge and the use of each of our virtues. Then we discover that the outside world may need our skills, which gives us great satisfaction.
Personal growth invites us to leave our comfort zone discovering that we can achieve goals that we did not even imagine before. The key is to work on ourselves to bring out our virtues. We must also avoid conformism, as we have infinite potential that we must take advantage of. If we want to achieve full happiness we have to apply radical changes in our lives. At first it may seem difficult, but the effort is worth it.
