This quote is saying that it is hard to find true love, but it is even harder to find true friendship. This means that it is difficult to find a person who loves you for who you are and with whom you can feel completely at ease and connected to. True friendship is even harder to find because it involves trust, comfort, and connection with another person. It involves finding someone who understands you and accepts your flaws and quirks, and who is there for you through the good and bad times.
