+1. Great advise.
Im a fan of Dave Ramsey's financial principal. Too much risk in single stocks. Sell it, don't forget about taxes, and put the money where you need it based on your financial life point.
This, BTW. Even if your brokerage takes out taxes (which they probably do NOT), take them out yourself and put them in a savings account where you won't spend them. You don't want to pay that difference at the end of the year.
If you don't know what the taxes are, this is the time to talk to a good CPA.
