When we are faced with problems, we should first try to solve them by ourselves although it needs more time than seeking help. Self–confidence is very important to the solution of a problem. Once we’ve overcome a difficulty that seemed beyond our ability to tackle, we’ll continue to face any future challenge bravely and wisely. This conclusion derives from a recent case I experienced. For a period I was perplexed that I had to press the button on the mainframe many times to start my computer every day. But yesterday it occurred to me that to start the computer a few minutes after it was switched on rather than immediately. Just one press started the machine. It also worked the same way today.
