Here is an example of a Happiness Clause. Obviously you should modify it to fit your needs. This one informs them that the lease will not be renewed, while that may be appropriate in some cases, I don't think most situations call for that.

"Home is where the heart is. We believe that everyone should absolutely love their home and that's the standard we've set for our company for the past ten years. Unfortunately, sometimes things aren't a great fit. We've noticed that you've experienced a consistent pattern of dissatisfaction with your home and our company's service.

We'd like to make that right. Effective immediately, you have the option to end your lease, for free, at any time, with a simple 30 days written notice and ending the lease at the end of the month. This offer will remain in effect until the final move out date of August 31st. This also serves as your official notice that your lease will not be renewed at the end of the term.
We'll continue to uphold all provisions of the lease on our end - including your ability to live in the home the entire duration of your lease term, should you choose, and providing you with the same level of maintenance and service that we do our entire portfolio. We hope that this option provides you with flexibility and peace of mind."

Here is a second example:

"I want my tenants to be happy in their home. You don’t seem happy and haven’t been for a while. So you can terminate your lease in the next 30 days for no penalty and we can go our separate ways. However, if you stay, this issue is deemed to be resolved and I won’t be addressing it again."
