Just reading 'Learning how to say no'.  This is the advice given.  'If constantly pleasing others is making you unhappy, it's time to increase your self-worth.  Next time someone wants a favour, don't apologise or give a reason, just say 'No, I can't help you this time'.'  Do writers of self-help books actually live in the real world?  I have never in my 51 years, remember hearing anything remotely resembling such a phrase being uttered.  And while on the subject of self-help books, note to self.  STOP FUCKING READING THEM!  I am only drawn to the ones that claim to not be self-help books.  Second note to self.  THEY ARE!  I have yet to read a single one that I haven't nearly passed out from boredom half way through but plod on I do, come across a few helpful tips, think 'ooh, that's a goodie, must try and implement that one into my life', completely forget about it as soon as the book hits the charity shop, then continue to live my normal existence, flaws and all.
