Happiness is a CHOICE. You prescribe your own happiness. It's really ALL about the mindset. You are the only one in the way of your own happiness. Yes, there is a lot of negativity in the world but to be happy you have to learn to see past that and focus on everything positive in your life, and love yourself over anyone else.
I completely agree with this quote. Sadly today it seems a lot of people have lost their ability to see things this way and have put priorities in a way later they may regret. whether you are a relative close friend etc.. I hope it is regained in society!
