Doubting

"Our doubts are traitors and make us lose the good we oft might win by fearing to attempt." -Shakespeare

This is my favourite quote, and i believe by it. But, i realised, doubting thyself can be beneficial at times. It keeps me in check. By that i mean reality check. It also serves as a form of managing expectations. Have found it useful to doubt myself in certain aspects of life, but of course i should know when not to doubt to avoid any detrimental effects.
