''The last three months have been tough. There have been a lot of downs, I won't say ups. But, I'm happy it's over and am looking forward to the Sri Lanka series,'' Harbhajan told CNN-IBN.
Harbhajan, who cuffed S Sreesanth during an Indian Premier League (IPL) match between the Mumbai Indians and Kings XI Punjab, was banned from the remainder of the tournament apart from being slapped with a five-ODI ban by the BCCI.
But, the 27-year-old is determined to put all that behind and firmly focussing on the future.
''I have learnt a lot from whatever happened and looking forward to start well,'' Harbhajan said. ''I faced a lot, but that is behind me and there is no point going back to what happened.
The bad times are over and I just want to focus on my game and keep on playing the kind of cricket that I have been playing for the last 10 years,'' the player underlined.
''I want to bowl and bat well and win games for my country and that's what is important to me,'' he added, saying ''I just want to enjoy my cricket and focus on it.'' The volatile off-spinner was unhappy after missing the Bangladesh tri-series and the Asia Cup in Pakistan.
''Every cricketer wants to play each and every game and I wanted to be there in Bangladesh and Pakistan. I also wished to represent the Mumbai Indians and play all the games. But, things obviously didn't go well,'' he said.
