A decision is means that make choice of two or more alternatives (Robbins, Bergman, Stagg & Coulter, 2006, p. 208). And it is the point at which a choice is made between alternative and usually competing- options (Fitzgerald, 2002, p. 8). Everyone would make any decision in their life time when they want to choose any ideas from alternatives, such as: to spend 3 dollars for coffee or 3.5 dollars for juice. Although it is very small things in everyone's lifetime, it shows that everyone will make decisions in our life by every time.
