I'm fixing point 1, which will free me to fix point 2 hopefully :)
Programming: Taking a job at a company where the Web department is in the Marketing Department,and only our 2-man IT department has access to writing anything more then HTML/CSS. Politics.
Programming: Thinking I could learn C++ architecture as I went and end up with a successful project.
I'm close to finishing up my Bachelor's now, I could graduate in June and throw myself full time into my business or I could do next year too which would be my Honours year.
Programming: Ignored the benefits of testing for way too much time.
Programming: Trying to create a framework that generates code.
> Any particular reasons?
Its a personal thing based on my lifestyle and might and not apply to everyone.
Programming : Not testing my code properly(I only do manual user testing). I still don't do it. I find it too boring. May be I'm too lazy to do that.
Programming: Switching majors from Computer Science to Economics (figured programming jobs would all be outsourced)
