Your biggest insecurity is today's topic. Over the years this has changed.
In my working career I worried about how I looked, how much I knew, how I was perceived, if I could learn what I needed, if I projected the right image, if I was smart enough. I was, but I never felt secure, always waiting to be shown up as a fraud.
At age fifty I stopped worrying and retired from the professional life, moving to part-time work at a much lower level and loving it. At that point I figured if someone didn't like me or the way I looked, it was THEIR problem.
So my current biggest insecurity? Worrying about the health and financial well being of my large, extended family. Health is currently good, financial well being varies...we all know the current economic climate. Here's to better times for all...and less insecurity!
Happily hopping through life,
