'It's through mistakes that you actually can grow. You have to get bad in order to get good.'

Paula Scher

This great advice for design students and professional designers alike comes from graphic design legend Paula Scher - but it's also worth attending to whatever you do in work or in life generally. Nothing on earth is created perfect, and it is only through trial and error - or evolution, of you like - that things improve.
