Ask: What are some of the scientific theories useful in life and career context?

10,000 hours of deliberate practice is one of the useful theories I've encountered http://www.psychologytoday.com/files/u81/Ericsson__Roring__and_Nandagopal__2007_.pdf

Are there any other theories you would add to this list ?

Any theories related to the following framework would be useful too
