Mistake #6. Taking on too Much
Are you a person who has a hard time saying "no" to people? If so, you probably have far too many projects and commitments on your plate. This can lead to poor performance, stress, and low morale.
Or, you might be a micromanager : someone who insists on controlling or doing all of the work themselves, because they can't trust anyone else to do it correctly. (This can be a problem for everyone - not just managers!)
Either way, taking on too much is a poor use of your time, and it can get you a reputation for producing rushed, sloppy work.
To stop this, learn the subtle art of saying "yes" to the person, but "no" to the
task . This skill helps you assert yourself, while still maintaining good feelings within the group. If the other person starts leaning on you to say "yes" to their request, learn how to think on your feet , and stay cool under pressure.
