I spent many years in senior management before going it alone, that job was even more lonely I found. Everyone above and below me came to me with there issues but there was no-one for me to go to. That said I am a bottler and tend not to flag up when I need help.
Now I just think about the politics, back stabbing and bitchy comments that were in the office that I worked. This really makes me appreciate the solo aspect of working alone.
It helps me to have a trip to my storage units a couple of times a day for a breath of fresh air, visiting clients is also a refreshing change and nice social event for me.
If you are a "life of the party" type (which I am not) it must be much worse to be working alone.
