Nobody deadlifts 200kg on day one

If you are saying, why can't I deadlift 200 kgs? So any gym trainer will tell you, start with trying to deadlift 20. Keep your ego aside and try to deadlift 20 first, then 25, then 30, so go in that way. So what is that method or practice which teaches us to deadlift 20 first? Doctors on the phone, son is unwell, wife is upset, all of these things are not the time to start practicing. You see, that is when we face the fruit of our practice. The time to start practicing is, room is empty, I have just woken up, I am just setting an example.
