About the future and other fears

When do you know whether you’re planning the future or just daydreaming your life up? What if I’m gonna wake up one day, working a corporate job, watching the same old movies, stuck in my head living with a beautiful movie star in a house I dreamt up somewhere on the west coast? What if all this pressure I put on myself only makes me scared to try? Having no backup plan has always somehow worked out for me, but what if it won’t this time? What if I never try because I’m afraid of failing? What would happen if I failed?
