Should I showcase failed client projects if the work was good?

Most times, it is important for the freelancers to showcase any task whether the ones that are good or the ones that are not. Doing this will make it easier for them to be able to win clients the more. There are some clients that only want honesty from the freelancers. They will be happy if they see freelancers fg are being honest showing their tasks even if they are not good. They only need to let the clients know what they have learnt.
