NEVER GIVE UP NO MATTER THE ERRORS YOU MAKE IN LIFE

I was one day working on my calculator project that I scheduled to do. I put a lot of efforts in this work to come out with the best of my strength. The project was to write a code to do a lot of complex mathematics.
After two months as I was almost done, I decided to compile and run my code after a lot of successful tests. Then there came an anonymous error that stressed me by playing hide and seek with me. I realized that was a lot work than coding the whole thing from start again. I ended up not accomplishing my goal. That is my story as a poor amateur programmer.
O. How can someone move on in life if one cannot locate the errors and obstacles that prevent dreams from coming true?
O. How can someone move on in life if one cannot correct the errors identified?
O. How is it possible to succeed if there are no preventions to curb such errors? Yeah, there are a lot of how�s to be asked and answered.

1. The errors we do are within us, they grow internally and get horns. These horns extrude externally for others to see how weird we are. So just find and replace before it becomes a talent.
2. Denying you being the cause of a situation is a serious error.
3. Errors within a man are like dusts, the fact that you don't know how the dust entered a sealed box doesn't mean the box is not dusty.
4. In all situations, find, correct and prevent errors before you move on. For the serpent which was not defeated in genesis turned to be a dangerous dragon in revelation.
