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. Have you so far accomplished all of your goals in life ? If so, 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,when attempting to visualize（形象化） or otherwise express what your goals in life are.

If you want, 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 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.
