Shakib Al Hasan feels his "ignorance" is to blame for his failure to report a corrupt approach resulting in his one-year suspension from the game.
The Bangladesh star was found guilty of breaching the International Cricket Council's Anti-Corruption Code on three counts and was handed a two-year ban (with 12 months of the sentence backdated).
Leading the team's Test and T20I outfits at the time of his enforced departure, Shakib's absence from Bangladesh cricket has been followed by a spate of losses for the Tigers.
The 33-year-old all-rounder said he had now realized his errors and pinpointed his negligent attitude that led to his implication in the offence.
"I have realized that there are certain things that you just cannot take lightly due to ignorance and probably that is the biggest lesson I learnt during this time," he was quoted as saying by DW Bangla.
Shakib, who is currently in the United States of America, conceded it was a difficult time for him being away from the game but also mentioned this extended rest allowed him to reconnect with his family.
"It is a very difficult time for me because at the back of the mind you always think that I am not playing or not being able to play. The good thing is that I was able to stay with my wife during the birth of our second child.
"I could not do that when my first daughter was born and I am trying to be with them in the lockdown. For me making sure that I am not depressed is extremely important as I am locked down in my house."
Shakib's return coincides with the dates of the T20 World Cup, implying that he might not make the cut for Bangladesh's squad for the tournament.
The veteran batsman deemed recovering his form as his top priority when he does make a comeback to the national fold.
"First of all, I want to return to the game. I will return to the game after 4-5 months. No other decision [will be taken] before that. The biggest challenge is to be able to start again from where I had stopped, that is what I'm expecting from myself.
"Wish I can start from where I ended. That is the challenge for me, nothing else."
Shakib had an excellent run in the 2019 World Cup, finishing as the third-leading run-getter in the competition.
Having batted all his career in the middle order, Shakib was promoted to the No. 3 slot in the 50-over event – a tactic that reaped tremendous rewards for him.
Talking about the inspiration behind his upgrade in the batting order, Shakib cited a conversation with South Africa's AB de Villiers during the Bangladesh Premier League, which had a major influence on his mindset.
"I was talking to De Villiers during the BPL before the World Cup. It was just a normal conversation. He told me that at times he has batted late. If he had batted at number three then he could have contributed more to the team and scored more runs," he said.
"Thinking about the team, he always had to play at four, five, six. His theory was to play in the middle order and score 70-80, which sometimes gives an advantage to the team and sometimes it doesn't work. But had he batted at three, then he could have scored 100-120 and might have won more."
