To understand why your character is driven toward a certain goal, get to know their positive and negative traits, as well as any significant emotional wounds that might be motivating them. Then you can explore the various kinds of conflict that could block them as they move toward their goal.
Sometimes a character will pursue a tangible (or intangible) desire at all costs. When it is ultimately destructive for the character, it becomes a toxic desire.
FORMS THIS MIGHT TAKE:
Getting high (a drug addiction) Numbing the pain through alcohol Pursuing psychedelic experiences in search of something greater Chasing adrenaline rushes via dangerous thrill-seeking (risky skydives, following tornadoes or violent electrical storms, playing with explosives, etc.) Chasing the big score (gambling) Giving in to a sex addiction Giving in to an obsession (a career, trying to "fix" someone, hunting a dangerous creature, etc.) Obsessively pursuing a relationship Needing to belong to a group, organization, sorority, etc. and doing anything to fit in Seeking perfection in some way (getting the perfect body via plastic surgery, going to any length to prove loyalty to a cause or person, trying to achieve the impossible, etc.)
HUMAN NEED DRIVING THE GOAL (INNER MOTIVATION):
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: A character may believe the only way to connect with their higher self is to use psychedelics in pursuit of a transcendent experience. They see the reward as being worth the possible risks (like permanent brain damage).
Esteem and Recognition: Characters with low self-esteem and low self-worth will seek affirmation from others. Sacrificing everything in hopes of being praised can easily become an obsession.
Love and Belonging: A character who struggles to fit in may find it easier to be themselves and let go of their anxiety while under the influence of drugs or alcohol. The ability to connect with others and forget their problems can cause a lonely person to remain in this state.
