There were periods in my life when I didn't have much, and I was unhappy because I wanted more.
There were times when I had plenty, but I was unhappy because I felt empty.
Now I have much less by choice, and I'm happier than I've ever been.
Don't get me wrong. I'm not suggesting that making a good income and having nice things automatically makes you feel empty or unhappy. Nor am I suggesting that being poor and struggling to make ends meet isn't good cause for feeling unhappy.
But I do believe that learning to live with less and simplify your life DOES improve your overall well-being. I also think that clarifying what is most important to you in life helps you recognize where and how you want to spent your time, energy, and money.
