Ser has its own conjugation rules if you are commanding someone to be a certain way. Although you wouldn't normally use the pronoun when giving a command, keeping them together while practicing can help you remember the correct conjugation form to use. For example, you might say, "sé feliz" to mean "be happy."   Tú sé: You be.  Él/ella/usted sea: He/she/you be  Nosotros/-as seamos: We be  Vosotros/-as sed: You all be  Ellos/ellas/ustedes sean: They/you all be If you're issuing a command to someone other than the person you're talking to, you don't want to use the imperative mood. The subjunctive mood is appropriate if you're telling one person to pass on a command to someone else. Conjugate ser just as you would in the subjunctive mood, adding the word que in front of it to make it a verb phrase. For example, you might say, "Diles que sean valientes," to mean "tell them to be brave." With some Spanish verbs, all you have to do if you want to make a command negative is add the word no before the affirmative imperative form. Ser, however, is irregular. As in English, don't use the pronoun before the imperative verb. For example, "no seas un cobarde" means "Don't be a coward."   Tú no seas: You do not be.  Él/ella/usted no sea: He/she/you do not be  Nosotros/-as no seamos: We do not be  Vosotros/-as no seáis: You all do not be  Ellos/ellas/ustedes no sean: They/you all do not be
