You are doing yourself a disservice when you say you need more time to prepare.
You don't need any more ideas, you just need to execute one.
Stop being jealous of others' 'talents' when they are actually skills.
Make the call, do the thing you've been talking about, learn the skills. It's more possible and achievable than you think, and it certainly doesn't require MORE experience and MORE time. After all “experience is something you don’t get until just after you need it.” — Steven Wright.
For the moment you might feel better, now that you've let yourself off the hook, but you're also slowly making yourself more and more miserable.
