The starting point of all achievement is DESIRE. Keep this constantly in mind. Weak desire brings weak results, just as a small fire makes a small amount of heat.

This quote is emphasizing the importance of desire when it comes to achieving goals. Desires can come in all different sizes, but to get the best results, you need to have strong desire. Having a strong desire is like stoking a fire, the more fuel and energy you put in, the bigger the fire and the greater the heat it produces. Therefore, if you have a strong desire to accomplish something, you are more likely to put in the effort and have the best chances of success.
