Perseverance
Any lasting change requires time and effort. Perseverance is the mother of change, that does not mean that it takes years to produce profound changes in our lives. You have to enjoy the process of personal growth that is developing along the way, as well as having patience if you prepare properly.
We have to learn to master our mind in order to achieve the goals we are aiming for and not to discourage the adversities that arise in the way of our personal development. Concentration is the basis of the mastery of our mind, when we direct the focus of our mind towards a single purpose the results will begin to appear.
