Not really, you're doing great!!!

...And therein lies the issue. We need to learn to stop hiding difficult criticism behind vague clichés and unhelpful positive feedback. 

As Brits, we are so preoccupied with being polite, not hurting people's feelings and trying to avoid feeling bad about upsetting someone that we are actually holding back our colleagues' development by withholding truthful feedback. 

Next time you think someone could have done better, be honest with them. Yes, it might smart for a moment and you might feel a little bad. But when they apply this criticism to their next project and see the difference, it's a win for them and win for you and the wider company.
