The world belongs to optimists..
People say hope is everything. Obama uses one word ‘hope’ and gets elected to the most powerful office in the world. Thinking positive always helps and gets us enthusiastic and energetic regarding the task at hand. A pessimist life is weak and dreadful they say..
But what about all those things that you expected to happen some other way but ended messed up? If you had expected them get messed up already, don’t you think you would have been in a more feasible position to work them out more efficiently? Then you would have had the best result without any risk. Even if you could not solve it and even if the work is completely screwed, you would be more happy than before because you already expected it to get screwed and did your silly best to make it any kind of better..so no disappointments.
In addition, thinking of the worst makes people active. Makes them work hard to avoid it at any cost. Hence better efforts..And more importantly the best thing about pessimism is that you are proved right or else you were wrong for your own good!
