"Unless you try something beyond what you already mastered,you will never grow" I agree with this argument because if people never try something new,they will never know if they choose the best option because never try. In my opinion be afraid is the worse thing in the world. In my experience afraid is the most thing that I feel stoped me because if I am afraid I never try something beyond things I have,even knowing that it can be better for me. Also if people try to do something new,they will learn more things than they already know. Keeping trying is the best option for all people in the world. Does not matter if they fail or they are wrong,and finally I agree with the statement because people will never know if they will get better opportunities in a job,college or in general life,if they never try or they never force theirselves to be successful.  First,if people never try something new,they will never know if the way they choose,was the best option because they will be always with the doubt thinking about what could happen if they were tried. They will never be brave enough if they never try to do something new because they are afraid. In my opinion the best example is when teenagers are in school,specially people who are from Central American countries,they are afraid because they do not speak the internacional language "Enlglish" so,they prefer do not try something like; speak with their classmates or even with their teachers,if they have any doubt they will never ask because they are afraid. They just do not want to try it because they are afraid classmates or teachers laugth about them,even when the teacher are good with them because some teachears are a kind of rude,not all of them but there are some of them. In my personal experience,the last year I had two teachers who was very rude with me and my friend. We were in our class when she asked for something that I did not understand and I asked her what was that,and she said that if we do not speak English we need to go back our conutry,and my other teachers was angry because in my class all the people was speaking Spanish and she said the same thing that my another teacher said before "If you do not speak English just go baxk to your countries". These are examples why teenagers are afraid to try new thins and they just prefer stay quite,but the only way to know how things are going to take place,is try it. If people try new things,they will be better person that they already are because they will figth for the things they want,they will be successful by theirselves.  Second,if people try to do new things,they will learn more things that they already know. When people try something new the results can not be always positive. They can fail,but at least they were brave to try something that they never try before and they have to be proud of theirselves even if they did not get what they want. However if they did not get what they want,they learned something new because people learn from the mistakes. Mistakes are the best way to learn because you will know what to do the next time that you try the same thing until you get what you want. Does not matter if you are wrong,you will learn because the life is a lesso
