Wow, amazing response guys, and i thought i was the only one who wanted to do everything by himself. If i wasn't so lazy, I probably would apply for a builders licence.
For me it was:
Customer Service (Retail) => Call-Centre Outbound (Telemarketing) => Call-Centre Outbound Sales (was on a contract with St. George Bank and was selling credit cards like bread and peanut butter
2 years ago?) => Dad => Website Manager w/ Sydney City Council (once again a contract job) => Running a small web des. busines while also studying full-time to be a highschool math teacher.
I considered doing TAFE teaching thing, I even asked my TAFE teacher where i was doing a part-time course in the evenings while doing my full-time job at SCC. She told me I really needed a TAFE Diploma first along with 2-3 years industry experience, and then you would do the adult teaching course... which would lead you into a pool of applicants (plus, they don't get the benefits & pay as school teachers do).
Note: Some of you guys should consider getting a cab drivers licence
For the future, I would like to get myself a short photographers course. Find out how difficult it is to get a REA licence. I would really like to set-up an online business for myself selling some sort of accessories (I have seen quite a few businesses selling their own products online). I could do tutoring but I've had a bad first experience (the kids parents were too annoying). I would really like to do something where I can make good use of my weekends while meeting alot of new people (although, i'm not so great looking guy which is the main reason stopping me from face-to-face sales).
BTW, i'm 21 years old atm. I plan to own 3 properties here in australia and 1 overseas for me to live in by the age of 30
