Caveat: Make sure you can generate 99 more compelling story ideas to demonstrate your growing skill.
Sometimes I wonder if it might be cagier to save your really good story concepts for your fourth or fifth script, and get the initial "learning scripts" out of the way with some lesser concept(s). This way, you don't waste your best, freshest ideas by trying to execute them them with undeveloped writing skills.
