No circumstance has the power to distract you from the direction you have chosen. Anything that knocks you off track does so because you have allowed it to. Keep in mind that you give power to your circumstances. You imbue them with your life, your purpose and your meaning. They are your reflection, not your essence.
The world around you can influence you to the extent that you allow it. There is a part of you that no one, no thing can ever touch without your participation. The direction in which you point and focus that essential core of your being will largely determine the quality of your life.
Pain and pleasure may both be quite compelling, yet they are outside of who you really are. Circumstances may be very alluring or terribly frightening, yet you exist beyond those circumstances. Keep that ever in mind, and be true to your greatest possibilities.
