Every once in a while, it is necessary to take a step back in order to take a long, hard look at where we are in our lives. At this point, it is good to ask yourself a bunch of critical questions. Are you at the point in your career where you want to be ? Have you so far accomplished all of your goals in life ? If so, then maybe it is time to make goals that stretch yourself a bit more. If you have not accomplished your goals in life, then perhaps you have made the mistake of setting too many goals or trying to accomplish them at an unnaturally fast pace.

It is necessary to set reasonable, intelligent goals in order to succeed in life. Do not be unrealistic because life is not a fairy tale. But you should try to recognize what you want, and to be as specific as possible when attempting to visualize(形象化) or otherwise express what your goals in life are.

In order for a goal to sufficiently motivate you, it needs to be a major one. The bigger your goals are, then the more motivated you will need to be to work towards accomplishing them. If you want, for example, to be the greatest concert pianist, in the world, then you are going to find yourself a lot more motivated than you would be if your goal were merely to, say, play a couple of Beethoven pieces extremely well. If you are a beginner, then no doubt mastering those tough songs is a very intelligent and realistic goal to set. But if that is your only goal as a pianist, then you will stop growing as a pianist once that goal has been achieved. This is why it is necessary to constantly stop and re-evaluate our goals so that we are aware of what they are, and thus stay motivated.
