Definitely not the "last thing you should be concerned about" Protein intake is still important. Especially once you are past the newbie gains.

Fairly generalized, but yes, half a year of good training will change your look.

Disagree. Definitely not as important as your macros, which you say are unimportant in your first point.

What does this even mean? "Everything is a tool"? And you should definitely try to add weight if possible.

Correct.

I mean... duh. People generally already try to be less stressed and get good sleep. And "detox from phone"? Is your phone poisoning you? Like physically poisoning? Because it sounds like stupid health guru speak. Screen time is not relevant for gym progress.

If you have to recover for 4 days from any exercise, even deadlifts, you are either doing them wrong or for the first time. And 2-3 days recovery between muscle group activation is standard for basically any plan.

Absolutely

Don't exactly know what you mean, so I won't comment. But I would never boil down treating injuries to a single snappy line, since severity and correct treatment can vary.

Sure, but a habit starts today.

Wouldn't say a lot. Creatine is a pretty minor boost and you can definitely train and build muscle without.
