In 2008, as part of her project Thời Gian và Tôi ( The Time and Myself ), She created her own company named Mỹ Tâm Entertainment (MT Entertainment). "Time and Myself"'s project has been planned to have five albums and a live show, and "is about those who always look back to the past to live a better future". She released her sixth album, Trở Lại (Come Back), on 17 April. Unlike Fly, the Korean producers were only in charge of recording and mastering the record. All the tracks were composed and handled by Vietnamese producers, including Mỹ Tâm, who produced "Như em dợi anh" (Like I'm Waiting For You). The album title expresses her return to the pop ballad genre with slow-jam and emotional feeling, and has a similar sound to her third album, but with the Korean influence. Come Back brought Mỹ Tâm to a new level in her career: a more professional voice, significantly improved English, and more skilled singing techniques (especially on the R&B track, "Và Em Có Anh" (And I Have You). Although the production is still Vietnamese, it contained a more international vibe, excellent quality, and characterized her as an evolving artist.
On 4 April 2008, Mỹ Tâm established the My Tam (MT) Foundation, a charity that operates on contributions from MT Entertainment, her fans, and others. "Nâng bước ngày mai" ("Sustain the Steps of Tomorrow") is a prominent, long-term project that has reached cities and regions including Ho Chi Minh City, Huế, Da Nang, Nghệ An, Gia Lai, Bình Định, Phú Yên, Cần Thơ, Đắk Lắk, An Giang and Hà Tĩnh. The project builds houses for the poor, and also has scholarships for the underprivileged. Every year, MT Foundation creates a lot of charity for poor people in the remote area.
