The more you have to explain things to people, the less “plain” it becomes. This applies to training situations, dealing with your employer who wants a reason you aren’t performing, and a variety of situations that require limited explanation.
The better you design your training manuals, the less you have to explain their contents to others.
The more forthright you are with your employer, the less you have to explain the reasons you aren’t performing like you should.
Remember – the better you develop your relationship with others, the less complex your relationships will be, and the more confident and strong they will become.
