There's one simple thing guys can do to be more open. And it has nothing to do with talking.
Back in the day, keeping a journal was a ‘manly’ thing to do. All the great thinkers, writers and explorers of the past kept a journal on a regular basis. With a pipe, a drink and a break in the day they would write everything that was on their minds.
As a psychologist, I believe MindJournal is one of the most accessible private methods for an individual who is looking for a way to help themselves feel better.
