Gratitude, like faith, is a muscle. The more you use it, the stronger it grows, and the more power you have to use it on your behalf. If you do not practice gratefulness, its benefaction will go unnoticed, and your capacity to draw on its gifts will be diminished. To be grateful is to find blessings in everything, This is the most powerful attitude to adopt, for there are blessings in everything.
The people who are successful are those who are grateful for everything they have. Giving thanks for what we have always opens the door for more to come, and ungratefulness always closes the door.
The feeling, "this can't be it", is a very powerful form of prayer. It's the agony of the separated self longing for reunion with wholeness. It's the call of your soul urging you to return to your own path and purpose. It's the force of evolution driving you home. Do not try to deny or override your divine discontent. Heed its call. Knowing "this can't be it" implies that somewhere inside you, you DO know what IS it.
There are two kinds of people in the world: those who make excuses and those who get results. An excuse person will find any excuse for why a job was not done, and a results person will find any reason why it can be done. Be a creator, not a reactor.
