This is what I wrote in a different topic...
well done - your first ton is one to treasure - actually im my book every 100 is one to treasure. The second one is just as hard because when you go out to bat you have to remember to start again on 0. Mark Ramprakash is the master of this.
Cricket is a great leveller - make sure you work really hard for you first 20 runs next time you bat, don't take anything for granted so that second one can come as soon as possible!!
You may not have got a hundred, but the message is the same, especially as an opening batsman, if you feel full of confidence and form fantastic, but the important thing is that the scoreboard says you start on 0 and you must play yourself in, it is a new day.
Work hard, try to reign yourself in for the first 5 or 6 overs, give yourself 20 mins or so to get used to the new conditions. Remember with the new ball a good one can come along at any time, but after 5 or 6 overs just by hitting the bad balls and working the singles you should be on 15-20 and back in the groove and really well set. Then look to build your innings ten runs at a time, or 5 overs at a time. If you bat for 40 overs you can score a huge hundred, but to do so you need to break your runs down... 10 blocks of 10 - remember you are there for the long hall as an opener.
Trust me as someone who has opened the batting at 11am for an all day game and been back in the pavillion at 1103 on more than one occaision, giving it away when you are in form is the worst crime a batsman can commit.
