The phrase "haddest mind to" is an old-fashioned way of expressing a desire or an intention to do something. Fortunately, there are many synonyms or alternative phrases that one can use to express the same meaning. For example, "feel like" is a casual and popular way of saying you want to do something. "Wish to" is another common synonym that conveys a sense of wanting. If you want to be more formal, you can say "have a desire to," "have an inclination to," or "have a propensity to." Other options include "intend to," "contemplate doing," "consider," or "entertain thoughts of." Whatever the phrasing, it's important to be clear and succinct about your intentions.
