Sachin, a master of his craft, understood his game and body better than anyone else, he knew what worked for him and prepared accordingly. Successive coaches/ physios/ trainers learnt to let him be, not interfere, because Sachin's preparation was meticulous, his routine settled.
On tour, he normally stayed in, kept to the hotel room, preferring music, movies and room service instead of going out for a meal. He ate early, hit the bed in time to get enough sleep but admitted to anxiety and nervousness ahead of every game.
His practise routine varied, depending on he felt about his batting. Not one to hit hundreds of balls or bat for hours in a net he opted for focussed training, working specifically on aspects that needed fine tuning. During the six week 2003 World Cup in South Africa Sachin hardly ever had a net, choosing to knock regularly -- this despite not scoring enough runs. Asked about his methods, he replied: I am batting well, so there is no need to aimlessly hit balls in the net.
