I worry a bit about it, in the context you've said. Job-wise: I'm a relatively young, female in a very man's world and I've been very lucky that my boss has put a lot of time and effort into my development.
I'd be lying if I said I don't get anxious before meetings that I might not get taken seriously or that I'm there in light of being politically correct, gender equality rather than my own merits.
But, I think it's a self fulfilling prophecy - if you tell yourself enough times something, you'll start to believe it and so will others.
A lot of people wrongly assume I'm a naturally very confident person - I'm not, but I am an extravert so I think that helps portray a different image.
I actually had neuro-linguistics programming (NLP) sessions to help regain my confidence with my horse-riding, but for me, it's had a ripple effect and it's hugely helped me in all area's of my life. It's been commented on by people that wouldn't know I've had it and certainly not for something horsey. It's definitely helped me and earlier this year, pre NLP I geniunely felt I'd had the stuffing knocked out of me and felt at an all time low. It was the first time in my life I've ever suffered panic attacks and anxiety.
I also (perhaps wrongly) see a lot of life to some extent as a conscience choice. You can choose to focus on the things you can't do, the things that aren't right or the things that might go wrong. Or you can focus on the things you can do, the things that are right and believe the best outcome.
Of course, other factors come into play too but I use a lot of the NLP stuff as part of my daily routine. It's been tough and quite frankly frightening at times (my own personal favoured approach to dealing with 'stuff' is to brush things under the carpet, not actually deal with things like my own emotions and feelings and pretend everything is fine. Yes, I'm stubborn and quite possibly emotionally stunted when it comes to these things
) and it's something I have to work hard on.
Of course, my life isn't a bed of roses but I feel more in control of how I react to things now.
