Hoy no es mi día Today isn't my day

Ser or estar. Hoy no es mi día, la vida es difícil — ser: what something is, what it's like in general. Estoy demasiado cansada, Mi jefa está enfadada, Estoy triste — estar: how things are right now. The narrator is a woman, so the adjectives end in -a: cansada, aburrida, contenta, tranquila.

estoy aburrida. "I'm bored" — with estar. With ser it would mean something else: soy aburrida — "I'm boring".

tengo sueño, hace mucho calor. todavía tengo sueño — "I'm still sleepy", word for word "I still have sleep". hace mucho calor — "it's very hot": calor is a noun ("heat"), so "very" is mucho, not muy.

Pienso que, me parece que. Pienso que la vida es difícil — "I think (that)…". me parece que todo es horrible — "it seems to me that…": it works like me gusta.

Todo el mundo, nadie. Todo el mundo mira el móvil — "everyone is looking at their phone": word for word "the whole world looks", and the verb is singular, as with English "everyone". nadie habla — "no one is talking": when nadie comes before the verb, you don't need no.

llego tarde. "I'm late", word for word "I arrive late".

un mal día. malo drops its -o before a masculine noun: mal.

tengo más suerte. Tal vez mañana tengo más suerte — "maybe I'll have better luck tomorrow": tener suerte — "to be lucky", word for word "to have luck". Spanish often uses the present tense for tomorrow, where English says "will".
