It is known that happy people think more happy thoughts than unhappy people. If we think happy thoughts... we create happy perceptions... we create a beautiful aura of light around ourselves... which leads us to happy events. And so we create a exciting circle (where we become even happier).
Happy thoughts connect us with the light, confidence and courage to act... to the power to believe. To live our lives according to our hopes and dreams not somebody else´s.
Jealous, angry and fearful thoughts and feelings take us away from our own path... our own purpose. But a straight path doesn´t admit compromises. This negative thoughts strip us of our power and ability to act effectively. If we think fearful thoughts we become afraid and act defensively. This pushes away other people and other possibilities away from us. And so we become lonelier and more afraid.
The route to a happier life is through happy thoughts. Not just because they make you feel better immediately... but because happier thoughts give you a stronger and more stable foundation to your life. You are in control rather than being bounced around by life.
