I used to think the word 'Ambition' was similar to greed or not being satisfied. It was not until recently that I stumbled on the true meaning of this word.
Ambition is a strong desire to achieve something. It is the desire and determination to achieve success. We should all be ambitious in our daily activities. If the government, citizens and working class are ambitious towards positive agendas, the world will be a better place.
I feel the reason ambition is usually seen in the negative light is because people put it in a negative context. If your motives and desires are bad, harmful and terror prone, and you have an ambition to put it in motion then you will make ambition a negative attribute.
Do good, be fair, stay positive and be ambitious in the right way.
