You are what you think about all day long.
You are also what you say to yourself all day long.
If you say that you are tired, lethargic, useless; this will be manifested by your external reality.
If you say you are weak and lack enthusiasm; this too will sadly be the nature of your world.
But if you say that you are healthy, dynamic, and fully alive, your life will be transformed.
Words have remarkable power on us.
Say to ourselves all the positive things and avoid all negativity.
We can actually make up our minds in an instant, if we want to, and hopefully change for the better.
Hopefully you can be persuaded to do the same :)
