Every dialogue you have leads to either understanding each other or talking about two different things. Sometimes we don't even realize the other person doesn't have any idea of what you were talking about.
Negative feedback is one of the things that makes us feel extremely uncomfortable to give. The strategy we mostly use with this is just avoiding it. Sometimes the topics become to pressing, that we end up taking a step towards approaching the person, to finally give the feedback. Many times we get just what we expected: it becomes a self-fulfilling prophecy.
Conflicts are something we usually associate with something negative. We associate it with fightig, war and conflicting opinions. In a stabe relationship it's not a problem to have two conflicting opinions or to simply disagree on something. The part that actually lets a conflict arise are our emotions, interpretations and evaluations. It's the way that we handle the conflict, perceive and treat the other person. We can be appreciative and still disagree on something or just enforce what we want on the cost of the other person.
When is comes to hiring decision, team fit and curiosity overrule skills and expertise. Someone can easily learn something new but adapting and developing your personality in a way that will make him a great team fit is not as easy and probably won't happen. Moreover, if you think for example of a soccer players: many excellent players that changed teams, didn't perform as expected because they didn't fit into the team. Some people even say that past performance, experiences and activities won't allow future predictions.
Goals are a great motivator. They help us focus our attention on relevant things, save us time and energy. To do this job right, a goal should meet some criteria, so it’s actually a real goal and not just wishful thinking.
There are different approaches to these criteria - depending on the goal and its context you would choose which ones to go with. The ones I'm mostly using are the s.m.a.r.t. criteria.
