Coaching skills are necessary even if difficult. 

It's important to establish what their goals/approaches are, how they feel about their performance or the situation,  and then ask to share your view. It was interesting to learn of the advice that coachees should do 90% of the talking in meetings and to learn how coaching is defined (or, more accurately, how it is not defined) because I would often interchange coaching with mentoring, training and providing feedback.

I have learned that how I say things can be just as important as what I am saying. Also learning that I need to incorporate flexibility and a heart to seek solutions when in conflict with another party. 

I have learned that negotiation means give and take and that I cannot be so rigid in achieving what I want. I didn't know of terms such as BATNA and ZOPA before this course, and will use my understanding to best prepare for any future negotiations!

I really appreciated all of the 2-3 minute videos detailing specifics of time management. My biggest takeaway was the video where 3 keys were discussed when you realize you are putting off a task.

It's important to recognize the many factors that go into setting goals, either for yourself or your team.

Not every problem needs addressing, and it's important to let those involved in a conflict take on the responsibility of resolving it.

There were so many good checklists and tips/tricks that I have saved to use in future written pieces (emails, reports, etc.). One takeaway that stood out to me personally was not dwelling on editing during your first draft. 

My biggest takeaway wasn't actually a new action item for me but rather a good reminder. I need to take a moment when I feel the stress building and reflect on my feelings so that I do not explode.

Feedback is difficult to give and more challenging to receive.  You have to be open to change and let your ego and emotions down.
