I agree, though in some cases coming up with your own ideas first can result in you becoming attached to them, because they are your own. It is unlikely for this to happen if you read the prior work first.

Though I think overall reading the prior work later is probably still a good idea, but with the intention not to become too impressed with whatever you come up before.
