Improv Yes Let's!
Anyone shouts an idea — "Let's all paint a fence!" The whole group roars "YES, LET'S!" and does it, fully, together, until someone offers a new activity — "Let's all be seagulls!" — and everyone commits to that. No idea is refused, ever. It is the purest "yes, and" drill in existence, stripped down to its core: accept every offer, and throw your whole body behind it. Players feel, physically, how good it is to be agreed with — and carry that generosity straight into their scenes.
🎓 Tips
The "YES, LET'S!" must be loud and unanimous. A mumbled yes teaches the opposite of the lesson — demand full-throated agreement. Do the activity for real. Half-miming while waiting for the next idea is where commitment dies. Encourage quieter players to launch ideas too. Everyone should feel the rush of the whole room saying yes to them.
