An infinite number of monkeys

Should I wait until I have something that may be of vague interest to say or, given how long I'd have to wait for that to happen, just write any old thing that comes into my head? Trouble is, I find other people's lives far more interesting than my own. Either that or I'm just nosey. Think I'll try and adopt the Michael Caine approach. Hopefully there'll be the odd The Quiet American alongside The Swarm, Jaws: The Revenge and numerous other aberrations.
