I'm 18 and I'm looking to give up on love, so I can accomplish my goals. One of the problems I face is the need to preserve myself. Having children is a way to carry on parts of myself after my death and is the method I came up with for overcoming my fear of death. Maybe there are other ways to preserve who I am, for example I could write down all my thoughts into books and people who read them will take on a part of who I am. What are the thoughts of others, on how I should overcome this need for having offspring?

Edit: I appreciate all the great replies, I can't really think of much to say other than a thank you, so this will be the last thank you: Thank you!
