Yep and it ain't easy and doesn't always pan out. As an example I sometimes train in the mornings at 430AM before work or after work by 6PM. Planned to train after work yesterday as normal, but ended up working 13 hours at office and another 4 at home. I had no expectation of an super long day, but it happens and I didn't get to the gym.
BB is best done in your early 20s before real life starts....before kids, before real jobs, before real responsibilties....when you're still naive and believe "I'll never give this up, life won't change me....I'll always look like I do now at 24!!"
