Bea,
It's how we progress, baby steps and learning as we go.
I'm also of the opinion that we do sometimes enjoy the adrenaline rush, however small, that we get when pushing the envelope. That's OK as long as it doesn't become the driving force, an addiction as it clouds our judgement.
I'm sure you'll find your equilibrium and progress at a rate comfortable to you but as you've experienced, there are external factors that can come into play so make sure you and your O are comfortable with possible outcomes/scenarios.
