Finally, I want to tell you that self-confidence and enthusiasm are the key to a successful life, and to succeed in any activity one is engaged in. We must be determined and must have an optimistic outlook, then even if we fail we will have no regrets. Firstly because the objectives were not realised, and secondly because you feel guilty and regret at not having made full effort in the realisation of the objectives. So therefore, whether we commit ourselves or not it is an individual choice. Once you have made up your mind, you must go forward with a single-minded devotion in spite of the obstacles. This is very important.
