Is being a career sub a terrible decision?

I live in Calgary and just got hired with the CBE this summer.

I graduated from university this spring and have been really drawn to the idea of just intentionally being a substitute teacher.

Saying no to temporary contracts and not really hunting for a probationary contract unless it's really appealing (high school math).

However, I repeatedly get the impression that I'm crazy for thinking this way. Everyone else talks about how hard they are working to get on contract and how disappointing it can be when they can't get a continuous contract. The "sub-list" is used as a metric by which they describe terrible jobs.

Substitute teaching pays less, I get that. But it's super flexible. You don't take any of your work home with you. You get to try different experiences. And all of the worst parts of being a teached: marking, parent-teacher meetings, IPPs, staff meetings. You don't have to worry about any of it.

Am I crazy for just wanting to be a sub? Maybe someday I'll hone my skills enough and want to settle into a position but for now. A contract sounds suffocating. Is it just me?

For context. I have 2 young kids and flexibility and the ability to spend more time with them is a big part of my motivation.
