Suppose your neighbor likes to repair motorcycles in his front yard during evenings and on weekends, and he earns $400 per week from this work. however, the sight of piles of greasy motorcycle parts and the additional noise and traffic caused by his customers reduces your value of living in this neighborhood by $500 per week. if your neighbor has a right to operate this business, how can you achieve the efficient outcome?

Planning for the future should be as important as planning any aspect in your life. when you retire, you will be faced with a big turning point in your life such as having to deal with your personal growth, your relationship with your family and friends, and finding purpose and happiness in life. you should be prepared not just financially, but emotionally and mentally. make sure that after all the work that you've done for all your life, you find the time to relax and enjoy your retirement with your family, friends, and yourself.
