Gumption- a must have to handle life situations. Do you have it in you?

Gumption- It's really a unique word, and a fascinating one too. The word really impressed me. I heard it recently in the movie 'The Holiday', where an elder character suggested the protagonist to have gumption to live a good life. The origin of this word has been mentioned to be of early 18th century (originally Scots). The dictionary meaning of gumption is "shrewd or spirited initiative and resourcefulness". Some of the synonyms which helps to understand the meaning are "initiative, resourcefulness, ingenuity, inventiveness, cleverness, shrewdness, acumen". Another meaning or definition which I personally like is "the ability to decide what is the best thing to do in a particular situation, and to do it with energy and determination". In other words "the strong will and determination to do something". Many a time, in your life, gumption acts as a prerequisite to handle or face a situation, but not everyone is lucky to have it. If one has gumption as a basic character or default property, he can easily play any ball life throws at him. In a few people, it might be present inherently, either in an active form or dormant state. When in a dormant state, it's sudden realization can change things drastically. In cases where it's not there, is it possible to have the gumption merely by realization or one needs to learn it? If later is the case, can we teach it as a life skill? Something to ponder upon.....
