Doing reading yourself can lead to bias. It's easy to project your hopes, fears, or expectations onto the cards, causing you to interpret them in a way that confirms what you already want to believe.
Also, when you are feeling highly emotional or stressed about a situation, your own turbulent emotions can sometimes make the reading feel confusing.
But doing it yourself can be good. You have complete context for the question. Since you know all the details, you can more easily connect the card's general meaning to the specific nuances of your life.
