The trouble with belief is that at some point it will be challenged. No matter if the belief is about your spiritual leaning, your understanding of yourself, or your belief about what motivates another person - try keeping your beliefs as open and flexible as possible.
Stay rigid and you risk snapping as a boulder rolls on to the tight rope of belief you are walking. By maintaining a softer more pliable stance, keeping your heart and mind open you will be far better equipped to stay on your path, no matter if there are times when you question your belief. There's no shame in changing your mind - in fact it's the only way to keep growing!
"It is not disbelief that is dangerous in our society, it is belief." - George Bernard Shaw
"If you don't change your beliefs, your life will be like this forever. Is that good news?" - W. Somerset Maugham
