inspiration challenges & obstacles colleagues & collaborators
i come from a long line of football enthusiasts. the assumption held by my older relatives that all of their male offspring would enjoy and play the game had never before been questioned.
when i was a young boy, a babysitter was switching television channels when she settled on a public television station that was airing a modern dance piece performed by a local troupe. i was transfixed.
a knee injury kept me from participating in any summer intensive or apprenticeship programs that year. i worried that the lost time would derail my career before it even began.
i was at a point in my career when i wanted to explore internal feelings and veer away from showiness. it was then that i met amber, a choreographer who encouraged her dancers to close their eyes and move from within.

Explanation:

1. For "I come from a long line of football enthusiasts...": This relates to challenges/obstacles as family expectations (assuming male offspring play football) could be an obstacle to pursuing dance. So it fits "Challenges & obstacles".
2. For "When I was a young boy, a babysitter... I was transfixed": This is about what inspired the dancer to be interested in modern dance, so it fits "Inspiration".
3. For "A knee injury kept me from participating...": A knee injury and worry about career derailment are challenges, so it fits "Challenges & obstacles".
4. For "I was at a point in my career... I met Amber...": Meeting a choreographer (colleague/collaborator) who influenced the dance approach, so it fits "Colleagues & collaborators".
