Self-help ✦ Penny’s Take
Positive Thinking
Kellie Sullivan · 2015
49/100
👎 Skip It
Kellie Sullivan frames positive thinking through psychology and health research rather than pure motivational talk, which is a reasonable angle. But the science claims here aren't sourced or footnoted anywhere I could check, so I'd take the 'research-backed' label with a grain of salt.
