Living a Simple and Stress-free Life

What can you say about the title of my post here? I believed millions of people would love to live a stress-free life. The question is? Can you live a simple life? For me, this is the key to be truly happy, living a simple but happy and contented life. Most of the times stress is caused by having complicated life. Stress is also caused by financial problems like having the inability to pay your debt. I heard a lot of people who are earning enough salary but still cannot manage their financial aspects in life. More on that, they don't have enough knowledge on how to rightfully manage and budget their finances. This is quite simple. Don't spend more than you earn. Lastly, in order to avoid stress, live simply and have contentment in life. Peace!
