Bury my head in the sand:

Means avoiding or ignoring a problem or a difficult situation instead of facing it - like an ostrich hiding by putting its head in the sand.

 Whatever floats your boat

Means do the thing that makes you happy, excited or satisfied even if it's different from what others think.

• Some people love to read classic literature, while others prefer fantasy novels. Whatever floats your boat.
• If someone says they're going to take up skydiving, you might respond, "That's a bit extreme for me, but whatever floats your boat".
