History blesses us with 20-20 hindsight. One obvious answer would be to keep my eye on technology and the evolution of computers in the workplace to stay, if not on the cutting edge, at least the leading edge of those changes.
If someone had told me that the course of my career would take me in many different directions and that I should be proactive and take some risks to step into those opportunities, instead of waiting for them to come to me, I would enjoy my career even more and with an even greater sense of achievement.
