No. You do not need a previous 'failure' in order to have a success: having a failure does not imply that the next excercise will be a success.
Unless you have understood correctly why the failure occurred, the next attempt is likely to be a failure as well.
It's usually unhelpful to label things as 'failures'. It's usually better to consider them as experiences from which you can learn.
