The word "should" often indicates an obligation or a recommendation, but it can sometimes sound too forceful or judgmental. Therefore, it's useful to know some synonyms that convey a similar meaning but with a different tone. For instance, "ought to" emphasizes a moral duty or a logical consequence. "Must" implies a compelling necessity or a higher authority. "Need to" highlights a requirement or a goal. "Have to" stresses a personal or external obligation. "Would be wise to" suggests a suggestion with an implied benefit. "It's best to" indicates a careful consideration or an expert opinion. Using different synonyms can add variety and nuance to your language and avoid sounding repetitive or bossy.
