I highly recommend the book “The Power of Habit” by Charles Duhigg. It describes lots of interesting scientific findings.

That book introduced me to a technique for eliminating bad habits that has worked really well so far. Duhigg describes a case in which a lady was trying to stop biting her lip, so she was asked to carry a slip of paper with her, and whenever she felt the urge to bite her lip, instead write a tickmark on the piece of paper. This ended up working for her (and for me) because it is apparently easier to replace one habit with another (i.e. lip-biting with tickmark-writing) than to eliminate a habit completely. And once you’ve fully replaced your bad habit with writing tickmarks, it’s easy to stop doing the latter - just stop carrying pencil and paper in your pocket.
