I've been working for 17 years now professionally.
I got an entry level job in the software development industry when I was 20 (and had dropped out of a Bachelors of Science in Biology program) and stuck with it, doing various jobs as time passed and project needs changed, for 10 years.
Like you, I never really had any "passion" for software in and of itself, or really "working" on computers in general.
Where I did find my passion was as an instructor.
I was asked to write all the user manulas and administrator manuals for a large, custom system my company built for a government agency.
I found out the following:
(1) I liked writing professional, technical documents.
(2) I liked teaching classes of 10 - 50 people at a time how to use the system and answer their questions.
I got entrepeneurial.
I wrote my own user manuals for MS Word, MS Excel, MS PowerPoint, and MS Access.
I went to a local computer shop that had a classroom and told them that I'd teach classes on the 4 core MS Office products at their classroom, in a 8 housr format (3 hrs. class in the AM w/ a 30 min break, 1 hour lunch, then 3 hrs. class in the AM w/ a 30 min break).
We charged $100 per person, and would not run a class unless we had 4 people or more.
The classroom held up to 10 people.
I kept half the money, they kept half the money.
So, in a day, I could make between $200 and $500.
It was a great little business.
I've also worked as a personal trainer.
If you're fit, you don't have to be certified, just patien and helpful to your clients and in the U.S. you can get $35-$75 per hour depending on what gym you work at.
If you train people at their homes you can charge $50 per hour because you are not splitting anything with a gym.
Only consider this if you like fitness and know what you are doing though, you don't want to hurt anyone.
