Everyone will experience a great many choices during his or her life. But at the same time, choices mean opportunities. The right choice can make a bright future in life. The wrong choice can destroy the dream of life. Therefore, selection is the process of pleasure and pain. Selection needs profound thinking skills, practiced judgements and careful attitudes. Also, it will take plenty of time. Selection is active and independent. It can be free to choose. But from time to time, selection is passive. In some solutions, you had to choose. However, all choices depend on yourself.
