My favorite method of converting to Bitcoin to PayPal is by using LocalBitcoins.com (LBC).
https://localbitcoins.comCreate an account there and verify it using your phone number. Once verified, you can send Bitcoin to your wallet within LBC. Earlier this year, they implemented a deposit fee, so you'll be paying a little premium for each deposit that you make into LBC. But don't worry, there's good news. You can find many buyers that offer a premium rate (usually 1%-5% over the going rate of Bitcoin) that will pay you more than what the BTC is worth.
Be patient, and only sell your Bitcoin to users that have a high volume of trades, as well as excellent reputation. There is a risk, as most sellers will only send the payment marked as for Goods or Services, which means that there is a risk of being able to be charged back at a later time. That's why it's important to find buyers who have excellent history and reputation. After doing this several times, you can "trust" a LBC buyer, and I'd recommend only dealing with buyers that you trust and have done trades with before.

I've had nothing but positive experiences with selling BTC for PayPal on LBC.
Another method? Go to the "Currency Exchange" board on these forums (
https://bitcointalk.org/index.php?board=53.0), and look for reputable buyers that will pay you PayPal for your bitcoin. You will more than likely have to send the BTC first, as a newbie, but if this is something you plan on doing regularly, you can establish some positive trust here by being a bitcoin seller that's easy to work with.
And lastly, be weary of websites that offer PayPal for your Bitcoin. The majority of them are scams, and the ones that are not charge exorbitant fees to do the trade.
