What’s the best way to build self-confidence?

I am not really the best person to give hints and tips on building self-confidence because as a character trait in others I find it can be built on pretty flimsy foundations. I would make a rather wild observation that often the most self-confident people build their confidence on the most unstable and unreliable foundations. So I view unquestioning or showy self-confidence with a fair degree of scepticism and distrust.

I constantly question myself and really believe that every day is a schoolday. Knowing that the foundations of my confidence are constantly under review might sometimes make me seem less than confident but actually I might just be reviewing and reflecting on new information or the shared wisdom of others. All waiting to be stored in my confidence foundations ready for future use.

So before building self-confidence always check that your foundations are sound, because self-confidence in the wrong hands is dangerous, unattractive and nothing to be proud of.
