Whenever I have trouble believing in an effort, and whenever I doubt a goal, it becomes impossible to achieve.
I'm not one of those people so optimistic that I believe you can achieve anything you believe -- to me that's nonsense. You still need the skill. You still need the training. You still need the discipline.
But even with all the skill, training, and discipline in the world you also must believe that what you intend is possible.
And then -- and then go do it.
Pick sensible goals (or go ahead, pick wildly impossible ones!) and then believe.
You will see how much more you achieve.
