"I will persist until I succeed."
Og Mandino
This quote is saying that he wont give up until he succeeds. He will continue to try until he succeeds. Thats how it suppose to be, you shouldn't stop trying until you succeed. Even if you fail the first time or second time or the 10th time. DONT GIVE UP!. You can succeed even if it isn't the first time. Succeeding takes its time. If you are determine to succeed you will succeed. Determination is the key to success. Being motivated is also the way to succeed. If you don't get a good grade the first semester in school. Try for the second semester. Be persistent, be motivated that you will do it.
