what will you do if you fail

It is generally believed that a man in an hole should not continue to dig if he want to get out. This summarises the title above. What will you do if you fail.
It is better to sit down and think so you can get a way out. The dead is the only one without a second chance move ahead. We are waiting. You are in a game until it is over it is not over.
What do I do:

• sit down and think 'why did I fail'. Is it that you did not put in more effort, dont have enough knowledge
• what SHOULD I do. Not what can I do. Go for knowledge to know what should be done in this situation. Oh, you are the cause of it please dont condemn yourself. If you are at fault acknowledge the fault and make amendment. No excuse is acceptable.
• Just Do It. Analyse but do something

Please remember it is your life, your success your achievement, your goal, your destiny. Only YOU can stop yourself. Go ahead dont stop. Remember Abraham Lincoln. A friend said Lincoln was only failing forward he eventually got to the highest point in his political career.
