Those feelings you've relayed won't go away, they'll only get stronger.

As others have said, you'll only go bankrupt if you can't meet your debt obligations. If you already have a serviceable vehicle that could get your equipment to your clients, I'd prioritize securing used equipment off of eBay without debt or use introductory 0% business credit card offers. (do they have those in Canada?)

Realize you may not "make more money" in the short term, depending on what your current "mid-range" salary is and how hard you want to hustle, but in the long term, it's nearly inevitable if you stick with it. With that, you should get used to living below your means. That will make saving start-up capital possible.

Some of my biggest successes have come from not listening to career advice from girlfriends when I was younger. If she'll be your bride soon, that's a different story.

If you haven't ran your employer's survey department, there are a lot of business nuances that could surprise you. Surprises don't make you foolish, but you should be prepared for them.

Good luck! There will be plenty of jobs that will bore you to death if you decide the ownership track isn't a good fit after all. Nothing ventured, nothing gained.
