We live in a world where we are not perfect and also we are likely to make mistake no matter the person you are, it's born to happen but accepting your errors and working towards it again is highly welcome to correct the mistakes.
The most important thing is that some mistakes are actually the road in achieving success because it requires trials to overcome it after several times. We as humans are not perfect but requires steps to succeed because we learn everyday to be perfect than our past.
The main mistake that can't be corrected is not learning anything to correct your error because that is definitely a wrong path to follow. Mistakes can come in any area of life which needs solution for it not to happen again, and for it to be handled properly in other for it not to occur again requires accepting your faults and working towards it to be corrected but as humans mistakes occur everyday and working towards it is a proper solution.
We should learn to accept mistakes and not look for a way to cover it up because that not actually the real way to be corrected. Some people fear this part and put the blame on others to be free and this is wrong and not helpful. Accept mistakes means accepting success because where a man falls is actually that same spot he will get up, in that aspect remove shyness or fear and move on, it will definitely help to eradicate your past mistakes.
The aspect of doing things yourself and not seeking help from others also is a wrong path and also another greatest mistake to do because there's a saying that says "two heads are better than one" which means that working together and sharing ideas or thoughts to a particular situation can definitely help with different ideas or solutions towards any problem. But keeping such to yourself will do no good but also will not make one move forward.
A person who never made a mistake, never tried anything new." Albert Einstien
The word of Albert Einstein goes a long way which explains one not trying to correct a past mistakes in the act of not accepting it and definitely such people don't bother to give such attempt another trial and in life for one to be successful requires several attempt to conquer a problem that needs solutions.
We shouldn't be afraid when mistakes occur, we should accept it and work towards it because it act as a lesson and path to correct errors we didn't realize before.
Never mind what people would say because they will surely talk both good or bad but the most important thing is to keep going and make sure you avoid been down or carried away with what you might hear because it won't help but accepting your mistakes and give it another trial definitely would have a success story to tell.
Never give up in pursuing your goals and stand up from where you lack difficulties to move forward because the path towards success would be rough and tough but the end would definitely be worth it.
