Speaking at Scotland's get-together at St Andrews, Berra tried to take some positives from the pressures and anxieties he endured in Edinburgh.
"I had a lot of ups and downs to deal with, but I feel I have come through it as a stronger person," he said.
"I think it will do me a lot of good in terms of my character.
"There are not many people who will have dealt with the things I've dealt with at Hearts and you learn from mistakes.
"I was 22 when I was made captain and the situation at the club got a lot worse after people like Steven Pressley, Paul Hartley and Craig left.
"There were times I thought 'Should I have taken this on?'
"But I had the armband at a big club and it helped me take a lot of responsibility. It made me a stronger person.
"Last season, the off-field stuff damaged us as a team. There was uncertainty over the management and coaching and it all had an effect on the squad.
"(Manager) Csaba Laszlo has come in and organised the boys and look how much better Hearts have done. I hope they get a European place, but sometimes it does feel like a weight off my shoulders.
"I am not the captain at Wolves so I can simply concentrate on my own job.
"I won't have to go to the manager's office after training and sort stuff out.
"There were always things needing arranging on behalf of the players.
"There were all the normal things a captain does and, at Hearts, it was maybe more difficult than it should have been.
"The media and the public knew there was a lot of uncertainty at the club, but I have learned from the whole experience."
The Edinburgh club, however, still hold a special place in his affections.
"I have a lot of feelings for Hearts," he said.
"Wolves are my priority now, of course, but after every game finishes I will be checking to see how Hearts fared.
"Laszlo has done a great job and I don't think Vladimir Romanov (majority shareholder) could have picked a better manager.
"I'm sure if he keeps doing the job he's doing then other clubs will look at him."
