Not only do you need to put your goals in writing. You also have to define your goals clearly and concisely. Focus yourself on your true intents. Intentions are ever powerful things. If you're not clear in your intents, you'll find it hard to keep your direction.
Be specific with your goals. Know the whys of what you're setting out to do. What are you setting out to accomplish? Make a list of your intents and work on at least realizing one every day. Give yourself a deadline for each one if you feel you need that as a motivator.
Every day, look at this list of goals. Focus on realizing your intents on a daily basis. Writing down your intents is powerful, but they derive their power through your force of action. If you keep your intents in your mind, they will drive your decisions and actions. Only then will the true steps to your greatest success become clear!
