One of the perks of my job is, I get to meet people who otherwise I would have never chanced upon. In recent times, I met quite a few retirees—senior citizens who are well into their 70s and one who is 94, and going perfectly strong. All of them are financially independent and extremely content with their lives, which made me ask them about how they are so content. The answer was simple—they all made a point, which somewhat summed up to: live within your means and be frugal with money.
