"Being at one with what is doesn't mean you no longer initiate change or become incapable of taking action. But the motivation to take action comes from a deeper level, not from egoic wanting or fearing. Inner alignment with the present moment opens your consciousness and brings it into alignment with the whole, of which the present moment is an integral part. The whole, the totality of life, then acts through you."-Eckhart Tolle

Knowing on a deep level who you are and what you need to do should give you peace.  You should feel that you are where you need to be.  If it doesn't feel right then you need to ask yourself questions.  I believe that true peace comes when you are on the right road for you.  It won't be the same as someone else but we are all connected but only one person can be on your road doing your work-you.  When you live now-in the present-you enjoy life more.  It isn't a destination-it is a journey.  Trust your heart.  Listen.  Peace.
