Karl Wald was the piano teacher of erskine, a modern American poet, novelist and outstanding pianist. One day, when he was teaching erskine, he suddenly asked him, "How much time do you practice the piano every day?"

"About three or four hours a day," erskine said.

"Every time you practice, is it long? Is there an hour? "

"I think this is very good."

"No, don't do that!" Carl said, "When you grow up, you won't have long leisure time every day." You can get into the habit of practicing for a few minutes whenever you have time. For example, practice for 5 minutes or 5 minutes before school, after lunch, or after work. Spread the small practice time throughout the day, so that playing the piano becomes a part of your daily life. "

14-year-old erskine ignored Carl's suggestion, but now it is really a wise saying in retrospect, and later he benefited a lot.

When erskine taught at Columbia University, he wanted to write part-time. However, classes, papers, meetings and other things completely occupied his day and night time. He hasn't written a word for almost two years. His excuse is "no time". Later, he suddenly remembered what Mr. Carl Wald told him. The next week, he put Carl's words into practice. As long as he has about 5 minutes free time, he sits down and writes 100 or a few short lines.

Unexpectedly, by the end of that week, erskine had written quite a few manuscripts.

Later, he also wrote novels in this way. Although the teaching work in erskine is getting heavier every day, there are still a lot of short leisure time to use every day. At the same time, he also practiced the piano and found that a short interval every day was enough for him to do two jobs: writing and playing the piano.

"No time" is always an excuse for lazy people. A short time, if it can be fully utilized without delay, is also very valuable.
