You must be comfortable with giving critique. Sometimes, you have to ignore the vanity of wanting to be liked for the sake of creating a brilliant product. Steve Jobs taught you that.
Just don’t go to his excessive lengths with this idea. There should be limits to your willingness to criticize. When you sense you’re about to dole out more judgments than suggestions for improvement, keep your critique to yourself. When someone is on the verge of breaking under the weight of pressure, your job isn’t to destroy and replace them, but to encourage and empower them. Build them up to the point where they can take critique and continue the noble work they’ve set out to do.
Think not of yourself in these matters, but in the success of your final product. Think about whether or not the work will be viewed as satisfactory, not whether you will be considered adequate.
