“…Happiness during infancy and childhood may be just as important as happiness during adulthood for initiating cascades of success and well-being (Coffey, 2018; Davis & Suveg, 2014). A primary marker of childhood success—education—is linked to earlier intellectual abilities, such as cognitive abilities and IQ (Abe & Izard, 1999; Ritchie & Tucker-Drob, 2018) and nonintellectual factors, such as emotions, emotion regulation, and relationship quality (e.g., Abe & Izard, 1999; Coffey, Wray-Lake, Mashek, & Branand, 2016; Dindo et al, 2017; Duyme, Dumaret, & Tomkiewicz, 1999; Davis & Suveg, 2014; Moffitt et al, 2011). As with happiness (Lyubomirsky, King, et al, 2005), intelligence and education are also linked to future success and well-being (Alloway & Alloway, 2010; Calvin et al, 2017; Lynn, 2010; Lynn & Mikk, 2009; Montez & Barnes, 2016; Ritchie & Tucker-Drob, 2018; Vaillant & Mukamal, 2001).…”
