to be a successful consultant / advisor

It is very important for a consultant to be an expert on her/his field, but is it enough?

Besides being an expert,

• be a person that can be consulted!!!
• be modest
• trust yourself and make people trust you!!
• take responsibility
• be a good listener!!
• follow what is going around
• be curious about subjects that you need to be but not more!
• be willing to learn
• know how to search and learn by yourself!!!
• create solutions instead of saying what is wrong!!
• ask good questions! 
• never say to your client they are doing wrong but make them aware what they are doing wrong and make them ask help from you!!
• be a good team player!
• be passionate about what you are doing
• be patient!
• be willing to serve your client but within the scope
• get all questions seriously and answer them clearly, even the most stupid ones!!
• make jokes but within the limits!
• learn to say "we" instead of "I & You"...
