You can say "no me importa", which is like "I don't really care," or as we Americans like to say, "Whatever."
Whatever that means... In Spanish, you would say "invertir en Dios".
cualquier hermano!
Lo que sea necesario
Sea lo que sea chica
There is no literal analogue to "I will" in Spanish. The "I will" part of every future tense verb in Spanish is integrated into the conjugation and is inseparable from it. So any Spanish "I will" will necessarily be tied intimately to a verb, whatever it may be. The closest it gets is to say "I will do [it]." To say "I will do" in Spanish, you say, "Haré." Pronounced: R- A, [English letters] with the accent on the A.
Whatever might not have a direct translation in Spanish. For example: Whatever happened with that guy? = ¿Qué pasó con esa persona? but, when you using it without context, like the typical way to dismiss things, well, it just does not have a translation in Spanish.
You say, "Tú lo/la* tienes todavía." *The choice of either 'lo' or 'la' depends on the gender of whatever 'it' is.
no tengo .... en mi mochilla/maleta ('....'stands for whatever it is you don't have in your bag)
the Spanish word for good is Bueno or Bien, depending on usage, so depending on what you're trying to say, you might say, whatever "es bueno."
Whatever is the correct way to say the word.
Ir al baño. You would have to conjugate the verb "ir" to whatever tense you would need it for.
