As we go through life we sometimes put up walls. Invisible walls to hide a portion of our psyche from others, walls to keep us from dialogue with others, walls to protect us from rejection, and sometimes walls to protect us from fears we may have.
Individuals attempting to circumvent laws and the authorities, for whatever reason, put up invisible walls so that few know of their wrong doings as possible. Sometimes, they make a mistake and that wall comes crumbling down. Their life can change for the negative when that happens.
People who have a fear of social settings can put up their invisible wall, appear apprehensive and or hard to get along with; but that front keeps them in their safe zone. When they figure out how to allow that wall to come down, their quality of life can improve; and they can actually find that tasks at work are easier because others are no longer fearful to interact with them.
I know a man very well in his early fifties, and he's always had a fear of rejection. He's had his invisible wall up his entire adult life and rarely shares his time with females. He also complains that he's always wanted a family, but women aren't interested in him. He's a super nice guy, but he hangs his head, looks down, and avoids any notion of a relationship. It's too bad, one life to live, and I don't think he'll ever get the help he needs to let that wall come crumbling down, even one brick at a time.
Some have a wall up to hide part of their psyche so that others will not see a side of them which they may find objectionable. One such young man I had doing some work for me several years ago was a closet racist. Deep inside he was angry. When he would get comfortable, he would cut lose with his true feelings. I ran across a website and one of the posters rhetoric sure seemed like Déjà vu. I made a comment that it could be him, and he said it was. I finally had to cut ties with him. I got a call one day for an employment reference for him, I knew the couple owning the company; and I had to tell them of his hard core racist views. I never did find out why he was so bitter on the inside. I wish he could have come face to face with his racist views, found a way to change, and lowered his wall. As long as he holds this bitter hate, others will eventually see it, and many good jobs could pass him by. Our reputations do follow us. Our co-workers talk, and many employers post completed applications prior to a final decision for current staff to clue them in on any potential negative past.
Think about what wall or walls you may have up; and think about rather it's hindering your quality of life. If it is, maybe it could be a life goal for you to work on and overcome. I've had various goals in my life to overcome, with the hardest ones being the invisible walls which hold us back. It's almost always a work in progress that will continue your whole life.
