I corrected the saying. Now it should have it right.
There is an old saying," If you fail to plan, then plan to fail". Meaning if you have a test coming up and you tell yourself that you won't pass it and that you will get an F instead of an A then you will. The other way to look at it is if you tell yourself instead, "If you pass to plan, then plan to pass." Then you will pass your test in life and see a better outlook on life. You will get an A instead of an F.
If you plan on failing then you might as well just give up, surrender, think there is no hope and pout and be sad.
Where if you plan on passing or winning, don't give up, keep going, preserve there is hope and happiness.
