When should you not attempt Hack Reactor(Galvanize)?

I work about 80 to 90 hours a week out of choice and have been since 2009, other than a semi-retirement in 2017/2018. I didn't do a bootcamp but I did a very competitive and selective college degree where 1/3 of students are mandatorilly cut after 1st year and worked non stop except for 1 hour a week on Saturday to go out for dinner. The work ethic that I developed then carried forward to the real world and I was very successful. That said, I have a lot of other weaknesses as a result and would not recommend this lightly. But my point is that the super intense intense work ethic carrying forward even a tiny bit might help you hit the ground running on the job!
