My first thought is Lord Krishna. I thought of Karma Yoga, which of course offers the path to freedom from attachment—and personalities developed by attachment to merit, fame or glory for example—by offering the fruits of action to him. When I can do this, I become free. Over the years, this has changed my personality. Of course, if you ask for a boon, the Lord may change you much more quickly. To me, Krishna is so loving and full of fun! The kind that comes from being supreme and most wise, then playfully melting my heart with that love, before showing himself as ALL.

My favorite chant for worship of Vishnu/Krishna is the Vishnu Sahasranamam.

Please note, I am a Western convert to Hinduism (since 1999), and enjoy making suggestions about things I love, but perhaps have not learned about the full tradition of those things.
