I'm thinking, I'm thinking!
Ok...I think you could do just about anything - you have diverse interests. For p/t, maybe consider (just ideas):
Veterinary assistant (you would be GREAT)
Animal handler/trainer or dog (pet) grooming, kennel work (always a spot for this job)
Gym worker, especially working with maintaining equipment (even cleaning); trainer/spotter for atheletes or those with disabilites, even children (for fitness)
Toy store! Sometimes (even restaurants) have 'play areas' that need monitoring for kids - you would probably have as much fun as they do!
Museum docent, particularly for children's interests since it's more 'hands-on.' There is a big need for this and you've got the talent. Some of these museum programs are great, even science-oriented (such as class field trips).
Teaching assistant in school for, say, art programs, play therapy groups (ie: children w/ special needs). They need a compassionate person with a 'playful' but responsible side - that's our Sid!
Maybe something outdoorsy? How about a recreational site - they often have school-type programs for children, and others, with teaching activities that are fun and educational, such as guided nature walks, nature-art activites, constructing snow-caves (or sand, whatever). Sometimes tourists participate in these recreational/wilderness sites - guided tours, etc.
Libraries often have GREAT opportunities for kids (of all ages); learning/play opportunities with a real need for monitors (Sid) to coordinate/participate. Sometimes they have art activities and libraries are quite high-tech! You would be perfect here too.
Maybe a craft shop; sometimes they conduct workshops (maybe doll making, toy trains, etc). You would be a natural. They do sewing, crafts too.
How about a senior center? They always need an enthusiastic someone - Bingo players here! Plus a fun and sweet/compassionate person to assist in all sorts of activites (ie: cooking, crafts, needlework, exercise groups, showing basic computer skills, etc).
Some Universities have health club, child-care, IT/library assistants, recreational activities - good place to check!
I'm sure any one of these would suit you well - plus more. Good luck Sid.
