Things I may want to do more/Other Interests:

  • High School teacher – I applied to university and got accepted to study Bachelor of Education to teach senior level Biology and Chemistry. I did not go as my subject I want to teach is Computer Science now. I may continue to study more computer science to earn a degree and then continue.
  • Practical Nursing – I started Practical Nursing and studied for a 1 year. I may want to complete this. I am somewhat interested in health care. It teaches me many life skills. I have a lot of friends in nursing and it is a secure government job.

Main Interest:

  • Building, setup and fixing computers. When I was in elementary school, all I wanted to do was to fix and setup computers like a computer technician and a bit of sales. I really wanted to open up my own computer store. I have grown more interests but building computers and setting them up is all I really like to do.
