It is important to know what you want, because life will deliver it to you. If you are not clear on your ultimate long-term goals, you will drift with the tide of life, always reacting to what it brings, defending yourself against its onslaught, directionless, a raft in an ocean.
Know where you want your life to go. Make decisions and take action toward that goal. Allow uncontrollable changes when they come. When you become emotional because the goal seems infinitely far, use icons to refocus your thoughts and give you long-term perspective on the immediate situation.
