I am always amazed at the way that life interaction is so influenced by ones own thoughts. Frown (even on the inside) and you will get nothing but the same in return. Smile (yes, even on the inside) and you will the same in return.
Don't believe me? Try it!
You have every possibility of influencing your surroundings. Not just the people ... life!
Every day you are creating your Karma, and every day it is creating you!
It is making you the person that you are. It is moulding you into you!
So be careful what you think, say and do. Because these are the things that you control, and these are the things that will define you.
And remember to always take it seriously, because it takes you VERY seriously!
