what would you do?

imagine you have the most regular life you can have. you have this work, from 9 p.m. to 16 a.m., with a lunch break around noon. you live in a rented house, and you pay all your bills by the end of the month. you have this girlfriend or this wife (or boyfriend or husband, it's up to you) whom you like and all. you live in a routine. and you know it, and deep inside of you you feel a need for something new. a desperate need, that have been crawling in the dephts of yourself since long. and then the opportunity arises, but not without a cost. it will have you shaking the very foundations in which your life is built upon. and without a promise of success. you don't know it will be worth the cost it demands of you. it's a shot in the mark, with a high chance of not hitting the mark. it's a giant leap that you take without knowing how you're going hit the ground.
