Obstacles are those frightful things you see when you take your eyes off the goal. – Henry Ford
No matter what, stay focussed on what it is that you want. Spend no time entertaining thoughts of doubt, worry or fear for they will only distract you from where your attention and energy is needed. There is only room for one image in your mind so make sure you always see the goal. Use your will power to ignore all pictures of that which you do not want.
