Even here, in the U.S., I walk my daughter's dog and I look for interesting people sitting at a picnic table and I walk over with my white hair and I ask, "Would you mind if I sat and rested here for a minute?" Nobody would refuse that.

Stay away from Europe, stay away from Japan, Australia. If you go to the Western world, you're gonna pay more money. You can spend five months in Bali for what you'd spend in one month in Europe.

I came back once or twice a year to visit my family, and then I would take off again. In the beginning, I think everybody thought I would get over it and get it out of my system. And I never did.

Risk-taking, trust, and serendipity are key ingredients of joy. Without risk, nothing new ever happens. Without trust, fear creeps in. Without serendipity, there are no surprises.

I don't worry about being a woman alone out there. My advice to people is to smile a lot, talk to strangers, accept all invitations and eat everything you're offered.

Eat where the people eat, not the hotels and touristy restaurants. If a local teacher makes $50 a month and they're living decently, see what they do.

If you don't talk to strangers, your life is so limited. If you're careful about what you eat, you'll never try anything adventurous.
