You can download a network card from the following links. Print them out and paint your network with paper and pencil. Consider first what areas of the sectors (eg industry) or the concentric circles are (eg proximity) could. Then you draw your contacts (for example, professional contacts). Each contact can e.g. be represented as a circle, square or triangle. Then paint the relationships (eg, professional relationship, friendship relationship) as the lines between your contacts. But be careful that you do not forget a relationship! It is best to go through each contact step by step, in a clockwise direction and from outside to inside.
Who has the most contacts? Who links the most, separated from each other contact groups? Have fun trying!
