Following your heart and letting god directs your step

Proverbs 16: 9 " In his heart, a man plans his course, but the lord determines his steps."
I love this phrase, and it really speaks out loud to me now, at this point of time, when I'm leaving a school where I have been for 5 years, where I have been very comfortable, where I have sink into the comfort zone, where I have become stagnant. And leaving for a new school with a totally new environment, totally new collegues, totally new students, new principal, and many many more new challenges.......
But then, what is life afterall, without new experience, without new challenges, without new perspective, without new risks to take.......
