Can I offer you some low self-esteem?
There has always been a negative connotation with low-self esteem whereas high confidence has been associated with positive attributions - i.e. confidence brings success, happiness, friends, money..etc.But being confident isn't necessarily all its cracked up to be. As Charles Darwin so eloquently stated, 'Ignorance more frequently begets confidence than does knowledge'. This means that knowing your limitations, and even underestimating your abilities can actually be more powerful than believing too much in yourself. I find this especially true in relation to your academic and professional life.In a psychological study done at Cornell University, students found that people who performed the worst in tests of logic, grammar and comedy also were the ones to have most overestimated their abilities. Those who performed better, were better aware of the limitations of their abilities. (http://www.apa.org/journals/features/psp7761121.pdf)
Evidently, if you begin to dwell too much on your limitations - because trust me EVERYONE has A LOT of them, it may prevent you from attempting new things. Having perpetually low self-esteem can lead to self-pity and depression. However, a healthy dose of low self-esteem is always good - it is better to err on the negative side as opposed to overestimations, as these could certainly lead to precarious outcomes!! Just be careful not to overestimate your abilities of underestimating your abilities!!
