Life as I knew it

Changes so often. I wonder at times if it is something to do with me. I worked for a year, then married and took off for another year while pregnant with the twins, then worked from home another year after they were born, worked full time whole carrying my daughter, quit after another year, relocated to uk a year later, and now going back to college and working in a totally different field all together! Ahhhh.... To tell the truth, life has been full and varied, but now I long for some consistency and my old work back! Teaching seemed very fascinating while in IT and IT looks exciting when in teaching! Its not that I don't enjoy what I have, my commitment to work has always been 100 per cent, yet, there is always the thought that I will only be happy with something that pushes me well beyond my comfort zone and I am not too sure that this job is doing that. Anyway, this post is just to clear my head..and I will greatly appreciate input for your end...have you had issues like these before? If so, how did you sort it out? If not, what would you do if you were me?
