from book 'Power of Now' by Eckhart Tolle

"If you are not in the state of either acceptance, enjoyment, or enthusiasm, look closely and you will find that your are creating suffering for yourself and others.Whatever you cannot enjoy doing, you can at least accept that this is what you have to do. Acceptance means: For now, this is what this situation, this moment, requires me to do, and so I do it willingly.When you make the present moment, instead of past and future, the focal point of your life, your ability to enjoy what you do and with it the quality of your life increases dramatically. The joy of Being is the joy of being conscious in the now.Enjoyment of what you are doing, combined with a goal or vision that you work toward, becomes enthusiasm. Even though you have a goal what you are doing in the present moment needs to remain the focal point of your attention."
