It's never ever a waste of your energy...
You can play at heat bending it in line and all sort of stuff.
I've even added side overlays on a bow like that to get the string across into line*.
It's how you can experiment and learn new tricks without the anxiety of spoiling a lot of hard work. If it turns out to shoot well, you can the pretty it up. It can also be a good give away as kids bow etc.
Never ever a waste of energy... unless you'd rather be indoors decorating shopping or doing some chores?
If you can put it somewhere warm/hot and airy it will season in a few weks now it's roughed out.
Don't over bend it until it's had a bit of time to dry out.
