To/For

[Super Sonic]

Hi.

I've been wondering what the differences between these three sentences are (or, if they are grammaticly correct).

"There is an art to sustaining happiness."

"There is an art to sustain happiness."

"There is an art for sustaining happiness."

Thank you in advance.

I would only use the first.
