"Let's do it tomorrow" - what a genius idea to waste a perfect opportunity and give the enemy time to finish everything they need to do. Go immediately after you've finished deciding what to do, don't waste a single second you dumbass. Of course, for plot reasons, the enemy will courteously wait until you're done planning and taking a year long vacation and collecting everything you need to defeat him and then not being bored and lazy anymore and appearing in front of him just so you can defeat him.
