There have been plenty of technological advances. And a lot more opportunities in life to advance yourself than ever before. Yet, it's all too easy for you to still suffer from low self esteem, feel empty inside or less worthy than other people. Beating low self esteem is NOT achieved by some easy gimmick or technique. Books are written about positive thinking.
People get rich giving seminars on personal growth techniques.
And you may have spent plenty of money on such techniques. Yet, six months later, you're in the exact same place as you were before with no substantial progress to show for it. The real key to making any real progress is that you need a strategy for building self esteem and experiencing inner transformation which takes into account the spiritual, mental and physical aspects of your being. The truth is that whilst mental techniques by themselves may work for a while. However, without a total approach accounting for Mind, Body AND Spirit - you will end up ultimately dissatisfied.
