Write about what you intend to be on future using future tense.

In the future I would like to become a successful author both with my present book and hopefully with future books since I believe writing will become a more and more enjoyable activity. While I am 72 years old now, I don't think of this as being that old and hope I may live to be at least 95. I will definitely need significant more time to fulfil my dreams now that I have matured and learned the true meaning of life. I also will wish to travel around the world in the future before I get too old to move much.
