O you agree or disagree? "Never stop trying to reach your goals."

hello

I am trying to improve my writing skills for the toefl, I wrote an essay about Do you agree or disagree? "Never stop trying to reach your goals." I would appreciate if you can correct it and score it, thanks a lot in advance

Many people may hold the opinion that we should never stop trying, while others believe that it is reasonable to give up after certain tries. I agree keeping trying even after a lot of failure because a success is gathering of all your failure, if you don’t fail and you don’t keep trying you will stay at the start point. I feel this way for two reason, which I will explore below

To begin with, no one will reach or achieve his goal from his first attempt. People fail and learn from their mistakes to do better next time. The experience of my uncle is a good example of what I mean. He is a famous dentist in Algeria, however before he becomes so, he went through tough time. He was not accepted in the dental school because his grades in high school was low, so he had to study different major for 4 years in a different city. And after that he applied again to dental school. He was rejected for the second time. He had to volunteer for one year in dental clinic to get the required experience and finally after 6 years he got accepted in the dental school while all his friends were making jokes of him but ne tried hard and he never gave up. Now he is one of the most famous dentist in Algeria.

Secondly, as is commonly known goals can be achieved gradually and cumulatively. For example flying in airplane was not found from the first attempt, it took the humanity years of trial and failure and patience. Some people even died while they were trying to fly and prove their own theories. Driving cars, exploring the galaxies all of that is the result of hard working and perseverance. Scientist kept trying years and years to find a medication for diseases and improve humanity lives.

In conclusion, I strongly believe that people should always try their best and never give up .This is because nothing comes easy and we develop through continuous practices and tries.
