My dreams are still out of reach/almost unachievable. What should I do?

I refused to believe “they might not have been for you” speech. If not, then what is? I have 3 dreams: be a writer, meet wwe wrestler Undertaker, & visit Tokyo. And I can't seem to make them happen no matter how I try. Mom says take one day at a time, but I fear time I don't have. I fear I could die. Tokyo is on a long hiatus. Who knows if I'll ever go? And there's rumors of Undertaker retiring. Thus, I only have my stories (that I fear people won't like/read). :(
