Ever noticed that you rarely give up on a GTA mission? Just think how many times you've said 'just one more go' when trying to do the RC copter missions. But are you so determined to realize your real-life goals? Grand Theft Auto always sets you a task and gives you a goal to strive for, be it winning the stockcar race in Vice City or becoming the owner of a magnificent abode.
So why not think of life in the same way? Just visualize your life as a set of objectives with tasks you need to complete in order to achieve them. Score well in each one and you could end up with a real mansion. No, really. You can do anything you set your mind to, man... and life's just a game.
