Star for you.
As a survival instructor I know what you say is true.
Failure will be more common than success in a real survival situation.
Whether it's trying to build a fire in the rain, make shelter than won't leak or find enough to eat you will fail more often than you succeed.
How to compensate?:
Learn from your mistakes.
Increase your awareness of your surroundings.
Be creative and adapt to new circumstances as they arrive.
Have faith you will succeed and never give up.
Of course the more knowledge you have and the more you have practiced various skills the less you will fail.
Give today's norm of instant gratification many will give up easily which is a recipe for disaster.
As my dad used to say people will need all the "stick-to-itiveness" they can muster.
