What is necessary can be a rather vague question. It really depends on what one feels is necessary in their life. If one just wants to live then it is necessary to breath, eat, and drink water. Beyond that it varies individual to individual.
What do I think is necessary? I think it is necessary to have a good education, a solid roof over my head, reliable transportation, and to have my family and friends near by. I think it is also necessary to treat other with the same respect that you want to be treated. I think a dependable job, good health insurance, and a solid retirement plan are also necessary to take care of me when I am old. I think it is necessary to live life to the fullest and to do your best at everything you do. Make each day productive. I think it is necessary to not get caught up in the daily rush and to take time out to enjoy the small things in life.
