very true. i got job very late and i was always thinking that teaching is very easy but unfortunately its the most tiring job, both mentally and physically. before teaching i did all kind of hardwork like filling tractor trolleys or ploughing in the field or most of the time painting houses etc but my tiredness will go away after few minutes of rest but the problem in teaching is that you're mentally sp much tired and without sleeping you can't get rid off. salute 🤗✍️
