I have the same fear as Augustus Waters in the movie The Fault in Our Stars. I fear oblivion too. I fear that I might live my life without any telos or end goal. Augustus said "Oblivion is inevitable, and that we're all doomed. And that there will come a day when all our labor has been returned to dust."
Going back to your question, my plan for the future is do something remarkable. What I mean by this is I want to create deep bonds with the people around me. I want to have an affect to their life. Accomplishment for material things will come along the way that's why I dont think of it that much. What I want to happen for the future is for me to be successful with the career path that I have chosen which is working online and eventually opening a business. All of my accomplishments will just be a part of my great plan, which is to share the fruit of my hard work to the people I love.
