How thinking big can make a difference in your life?

It tends to be a human behaviour that when someone talks extravagantly, other people see him as an idiot; we are not designed to see a person in a jogger and Hyundai dreaming about multi-million dollar business and other luxuries of life. We are taught to live and dream within our limits/ economical status. And, that is the reason most people do not think big. They are afraid of being exposed as an idiot or not practical.
If you think small, your world will be small. If you think big, your world will be big.
– Paulo Coehlo
I may sound like ambitious(idiot!) but everybody should start thinking big regardless of their limits in life. For example, if you think of building a small successful clothing boutique business why not add a few other franchises of your store and multiply your income? You have to work the same amount of time, it takes the same efforts to select product line, interior & furniture of the store, marketing efforts but just adding another store in town can multiply your income. You shouldn’t be a prisoner of your vision, let go off your inhibitions.
Thinking big doesn’t mean that you have to work more, sacrifice more to achieve something more than regular.
Life is all about finding a purpose and working towards them as much as possible. You will definitely fail, think to give up, faced resistance and lack of supporters initially but do not stop thinking big! Even if you fail at this level, you will fail big with experience and lessons and that can be your biggest asset in your life. There is no person in this world who has not seen failure. Failure is inevitable!
However, there is a sunshine end of the tunnel. And, one day when the tunnel ends and you will meet success if you stop thinking big, the success will be so small that it is not worth all the effort you have put to achieve it. When you can hit the moon, why to aim for stars?
Conclusion:
Thinking big is not a sign of idiotism but a sign of progress and motivation. It has no relation to your current situation; either you are just starting or doing reasonably good, you can always keep thinking big to achieve the best out of your life and upgrade your success to the next level.
