Read the passage carefully and answer the following questions:

Progress in life depends a good deal on crossing one threshold after another. A little boy tries to write his name, it is a hard work, very hard work. Then he arrives at a threshold and writes his name with comparative ease. Now a new threshold confronts him. This is the way with all of us. As soon as we cross one threshold by achieving a certain goal, a new goal appears, or should appear. Some people make the mistake of steering clear of threshold. Anything that requires genuine thinking and use of energy, they avoid. They prefer to stay in a rut where thresholds are not met. Probably, they have been at their job a number of years. Things are easy for them. They make no efforts to seek out new obstacles to overcome. Real progress stops under such circumstances. Some middle-aged and elderly people greatly enrich their thresholds. One went into an entirely new business when he was past middle life and made a success of it. De morgan didn’t start to write novels until he was sixty. Psychologists have discovered that a man can continue to learn throughout his life. It is undoubtedly better to try, and fail than not to try at all. Then one can be placed in the category of the Swiss mountaineer of whom it was said, “He died climbing.” When a new difficulty rises to obstruct your path, do not complain. Accept the challenge. Determine to cross this threshold as you have crossed numerous other thresholds in your past life. In the words of the poet, “Do no rest, but strive to pass from dream to dream.”
