If you look at life through a lens of negativity, life will dutifully arrange itself to meet your expectations. When you approach life from a more positive perspective, your expectations will just as surely be met.
Is it unrealistic to look at the bright side, to remain generally positive, and to expect the best in life? No, because reality itself is neutral, and what you get from it depends upon how you view it and what you make of it.
The raw forces, circumstances and events are, for the most part, out of your control. Yet you can completely control the way you perceive, respond, adapt and yes, even prosper under their influence.
The control you exercise over your own perceptions, thoughts and actions will make all the difference in your life. Reality is what it is, and your own relationship to that reality is precisely whatever you choose for it to be.
There is goodness, there is beauty, there is love and joy and boundless opportunity when you choose to see it. Look realistically at the world, see the very best, and bring it joyfully to life in each moment.
