Optimism can only be rewarding if one takes action. Without it, it’s like driving a car that runs out of fuel; you’ll never arrive at your goal. Your past mistakes or apprehension about the future has nothing to do with what you can do today or what you should act upon. Decision-making may be risky but there are great results if it is coupled with a conscious effort to do what is right.
People are generally reluctant to kick start their plans right away because they are either afraid to commit mistakes or they can make foolish decisions. They dread of becoming listless, indifferent to taking a step to realize their potential.
