Boonchai Bencharongkul

He is the founder and chairman of DTAC, Thailand's third-largest mobile phone operator.

Boonchai was 27 when his father died in 1981, leaving him the business as well as a lot of debt amid numerous lawsuits.

He eventually persevered, closing down and offloading some branches of the business, and shifted its focus to the growing telecommunications industry.

In 2012, he built the Museum of Contemporary Art in Bangkok to showcase his collection.

[3] Personally, he is a follower of the Dhammakaya movement—he found that Buddhism and meditation had helped him through his father's death and the financial crisis.
