Can I say "in my life" instead of "with my life" here?

No, it would not sound as natural to say "in my life" here instead of "with my life". This is because "with" indicates use in this context. He is talking about what he wants to do "in life", however, he is expressing also what he should do with his past life experiences. Thus, he uses the preposition "with" to express the use of his life.
