Organizing and planning our activities is always a good thing in our life. We don't forget anything if we organize our work in a manner. Having a plan for future is also a good thing, but don't waste your present for planning about future a lot, also it is not good to live without any aim and target. We must live our life in a balanced manner to enjoy it fully. So plan for future and work for it, don't spend all your time for thinking and working for future, allocate some time for your present and get some relaxation and refreshment to enjoy your life.
Having long term plan is good. Plan for the good and work to achieve your aim and target, a life without aim is nothing. So have an aim and work for it. All the best to achieve a lot in your life.
