There are five basic human needs that, when missing from a character's life, could motivate them to pursue this goal. The following needs are all possibilities, but only one of them should be the primary driver for any given character. For more information on the relationship between human needs and outer motivations, please see​ this ​Character Motivation tutorial.

Self-Actualization: This need would be impacted if the problem's solution would help the character feel more fully actualized, such as them solving a problem impacting society or inventing a product in an area of their passion.
Esteem and Recognition: The character's esteem may be at risk if the problem is one that lowers his opinion of himself or other people's opinion of him. This could be the case if the character is failing at school or struggling with a sport or artistic endeavor, for instance.
Love and Belonging: A problem that exists with a parent, sibling, friend, or love interest could cause them to feel a void in the love and belonging department, pushing them to find a solution in order to fill that need.
Safety and Security: This could become an issue if the problem needing a solution is a safety issue, such as an untrained pet that constantly escapes the house and runs into the road.
