While pursuing success, a lot of things are on our mind. Sometimes we focus on how to be the best at what we do. We seek perfection, accuracy and give ourselves no room for error. Although perfection is needed in completing some tasks whereas being fixated on it in all things can be counterproductive.
We often try to be better or do things better than others. This can be good if your objective is to honestly seek improvement and not just to boast. We seek differentiation and that is good but a lot of focus on just being different can drain our energies.
Human beings are not perfect beings. They make mistakes and learn from them. A key ingredient is perhaps, perseverance.
