I love psychology！When I was an undergraduate I read a lot of psychology books and take some courses which totally change my life .

I figure out that introduction to psychology is pretty boring to me because it is too broad and not relevant with everyday life ,so I highly recommend to learn two significant branches of psychology:

Positive Psychology :https://positivepsychology.com/harvard-positive-psychology-c... Great course taught by great teacher.

Cognitive bias:https://www.amazon.com/How-Know-What-Isnt-Fallibility/dp/002...

Modern psychology is very interesting and powerful，enjoy it！
