A vital element of being happy is to continuously develop your sense of inner peace, which means that you're actively working on healing the difficult issues in your life so that you can become the healthiest you possible. When you have inner peace, you treat yourself and others well and live a life of greater kindness, love and harmony. There's no mystery to feeling peaceful, you either decide that it's important to do or you don't.
When you possess inner peace you will notice that you're calmer and are able to handle anything that comes your way, which in turn will make you much happier. It's the difference between someone who lives life struggling all the time and someone who is healthy and balanced and enjoys the journey. To become more peaceful inside try spending five minutes each day meditating. You don't have to worry about what technique you use or whether you're doing it correctly, just sit alone in a quiet place with no interruptions, close your eyes, and slowly repeat the word "peace" over and over. As you practice being still and present you'll gradually develop inner peace.
