Probably the best advice I ever got was to never compare my achievements against what others around me have done.
Unfortunately, or fortunately I am only now beginning to realise the true value of that advice. Where has it been for the last 40-ish years? And why was it not something that my teachers at school taught? I’m sure it would have saved me much angst over many a stupid, dumb thought going around and around in my head.
So now I try not to compare myself against what others have achieved – it doesn’t work all of the time but apparently practice makes perfect.
