Earlier quoted context omitted.
“Lazy” is the wrong word. People work for 8 hours a day and then are expected to cook, clean, exercise, and maintain some sort of social life. Adding in Leetcode on top of that is going to cause something to give. There’s only so many hours in the day.
Regardless of the exact word choice, if you have a life goal that requires some extra effort and sacrifices, and you cannot get yourself to do it, you can't really blame your busy life or anything else. There are others who do all of the above and still make the time, and they are going to be more successful than you while you continue to complain about the industry/interview process/leetcode/whatever else.
That grind set mindset, “you can do anything you set your mind to, so you can only blame yourself for not having {life goal}” is a recipe for depression and burnout
