Growing up, Ms Ruby Pan wanted to be a writer. In her teens, she fell in love with the theatre and dreamt of being a playwright.
She won a Public Service Commission teaching scholarship to study English literature at Princeton University in the United States, where she bagged prizes for a play and a collection of short stories she wrote.
She even got to perform a monologue she wrote at a show produced by the famous Royal Shakespeare Company in England.
She thought she had done everything that was artistically fulfilling, but when she graduated in 2006, she felt no joy.
She says: "Instead, I felt burnt out, like I had run a very long race for no reason."
Ms Pan, 31, who now goes by her ordained name, Thubten Damcho, was speaking over the telephone from Sravasti Abbey, a Tibetan Buddhist monastry in a forested area in Washington in the United States, where she now lives.
In 2007, after returning to Singapore, she started teaching English language and literature at a secondary school here and was in charge of its drama club.
She dated, partied and ran arts workshops for volunteer welfare organisations. And yet, she still felt dissatisfied with life in general. At a friend's suggestion, she signed up for Buddhism classes at Kong Meng San Phor Kark See Monastery.
The teacher, Venerable Chuan Guan, 42, "exploded" her notion of what a monastic should be.
She recalls: "He was well-educated, humorous and explained Buddhist concepts in a logical and practical manner."
One day in class, she learnt what "true happiness" was.
The venerable drew a picture of the six realms of existence in Buddhist cosmology, and showed how the Buddha had gotten out of the cycle of rebirth.
She says: "By transforming his mind through moral conduct and meditation, he was no longer subject to an uncontrolled cycle of mental and physical suffering, and was able to benefit others.
"And I thought, 'That's what I want to do with my life! I wanted to follow in the Buddha's footsteps.'"
