Joni Mitchell
Joni Mitchell is exactly what you'd expect a starving hippie artist to look like in the 1960s. She spent much of her time in Canadian playing cheap gigs before she got her start. In her early 20s, she was discovered by David Crosby and flown out to LA. She won her first Grammy in 1970.
Barbra Streisand
Streisand gave up everything for her art at a young age and spent her teenage years and early 20s crashing on friends' sofas as she traveled. She pursued a singing and acting career, and her powerhouse vocals landed her countless roles. However, she never forgot her humble start as she rose to fame.
