Likewise, if you are not certain which notes to play on a given bass line just make up something but play it with authority and confidence and then repeat whatever made up notes you played the first time exactly the same way at least one more time. Everyone will just assume it's your artistic interpretation of the song.
Said another way - a wrong note played once is a mistake, but a wrong note played twice is artistic interpretation.
