To be driven by positive expectations, verses negative avoidance, is the sign of someone with an amazing future ahead of them. Aside from the manifestation principals behind this, the sheer motivational aspects of this are huge.
Fear has its place - you would likely do more to keep someone from stealing $100 from you than you would to earn $100. But, fear doesn't get you out of bed, in a positive state, quite the same way that passion does.
If you love life, and are driven by your ultimate, positive goal, your life seems better. The better your mood, the better those around you feel, and the more likely the universe is to help you out. Not just on the metaphysical side, but, think about it: If you've ever worked in the service industry, who do you want to help first? The crabby lady, or the nice lady? Who would you chase out into the parking lot if they forgot their visa card? Who would you go that extra mile for?
Never be afraid to have positive expectations. In fact, grab your goal list, and ask yourself honestly: Which goals could I improve/upgrade?
What would you attempt, if you knew you could not fail?
