"To achieve the impossible you have to see the invisible" - @andyfrisella
You have to have a vision. Without a vision there is no incentive. You literally have to see yourself where you want to be in 5, 10, 20 years. Picture yourself owning that business, building that dream home, buying your dream car, establishing a family. Do and let NOTHING get in your fucking way from doing so. As long as you can answer the question, where do you see yourself in the coming years. If you can answer it down to the detail and I mean DOWN TO THE DETAIL, meaning you have done your research and planned for it, then you are on the right track in achieving the impossible.
