mominca: Congratulations! That is amazing! Apple at a cost basis of $1.65 and it's now trading at $211 (or so). You get almost twice your cost basis annually in dividends. The power of the US stock market to generate wealth is like no other.
If you hadn't sold a share, it'd be worth $1.9m today. However, life is as it is and you still have to pay your bills no matter what. When emergencies arise, then it's nice to have alternatives. And, of course, there is no way to have known back then where the stock would be today--maybe it'd have been like Enron, GM or all the others that went belly up and you would've been very wise to cash out. All in all, it's a great story--part of your life!
Since it sounds like you're in good shape financially and don't need the money now or anytime soon, I'd encourage you to think long term. Very long term, in fact. You could set some of the stock aside for your child(ren) when they turn..... 30? 35? Not too young or else they may be too young to appreciate the value of money and squander it on poor decisions. Or maybe set up a trust (?) for your grandkids, for when they turn 30 or 35. It seems like ages away and it is. But you have the potential to secure the next generation(s) place in the middle class. Why not take it? YMMV.
