In other words a project, phase, or relationship begins, then takes on form or structure, and finally needs to be reorganised as circumstances change and begin again. So the cardinal, fixed, mutable process continues as a time goes on. Those heavily influenced by the cardinal signs tend to be full of initiative, have no problems in beginning new projects and are usually quite busy with new plans. Within a group setting, the cardinal signs are most likely to lead others through their enthusiasm for the group's aim. Aries tends to express it's cardinality through the world of firsthand experience and pioneering activity.
Cancer seems to be motivated by activities that satisfy their moods and emotional needs.
Libra tends to be motivated by the need for inspiring communication between both individuals and groups. Capricorn tends to express itself through achieving material rewards and be motivated by results. Those heavily influenced by the fixed quality are great at using their energy to keep long term projects running smoothly and for situations that require patience. Using the match example again, I would see the fixed signs representing the flame that slowly but steadily burns through the matchstick until it reaches the end. Taurus seems to have a need to hold on to it's resources and material possessions.
