The smartest things I ever did..........well there are lots but to me the process rather than the content is more important. So my answer is visualising what I want and setting really tangible goals and then committing 100% to them. So the smartest thing I ever did was goal set, then set new goals and go for them, set goals in all areas of my life and link and sequence the goals and imagaine achieving and living them now. If you don't achieve the goal ask yourself are you nearer or further from what you want and then reset the goal........etc
