What’t the difference about “-아도/어도/여도" and "-더라도" ? 질문이 있습니다.For example:⑴나는 아무리 만들더라도 쓸모가 없다. (2)나는 아무리 만들어도 쓸모가 없다. Is it the second sentence right? or,why?

Aftering After graduated from senior high school, I had seen an article and learned more from it. It said you could overcome many difficulties and you knew many knowledges about the subjects what you had learned before you graduated.Such as Mathematics, Chemistry,Physics,English,Biology,but after that,you became more and more ignorant.You won’t try to do exercises again with your knowledge, and you don’t know how to wake up you strong will when you facing obstacles.I can’t agree this point more. In my view of point,difficulty is a trouble the world bring to you,but it also a gift the world give you.What’s the role it take in your life depend on your choice. PC：please don’t laugh at my poor english and help me to improve it.
