¡El amor! Cuando estamos enamorados el cerebro libera una sustancia llamada feniletilamina, la cual suprime la sensación de hambre y sed.

Through thick and thin
¡Contigo pan y cebolla!

To split hairs
Buscarle (los) tres pies al gato

Better safe than sorry
Más vale prevenir que curar

Desperate times call for desperate measures
A grandes males, grandes remedios

To play by the book
El agua clara y el chocolate espeso

To be a Jack of all trades
Ser un todoterreno

To get down to business
Manos a la obra

You scratch my back and I'll scratch yours
¡Hoy por ti, mañana por mí!

To kill two birds with one stone
Matar dos pájaros de un tiro

To grab the bull by the horns
Coger el toro por los cuernos

Doing work you enjoy isn't a chore
Sarna con gusto, no pica

The early bird doesn't always catch the worm
No por Mucho Madrugar, Amanece Más Temprano

The early bird catches the worm
A quien madruga, Dios le ayuda

To look after number one
Barrer para casa

To help out
Echar un cable

To have connections
Ser o estar enchufado

Haste makes waste
Vísteme despacio que tengo prisa

To make a mountain out of a molehill
Ahogarse en un vaso de agua

Rome wasn't built in a day
No se ganó Zamora en una hora

No worries, you'll find it!
Lo que no se comen los ratones, sale por los rincones

No gimmicks, no tricks
Sin trampa ni cartón

To handle things tactfully
Tener mano izquierda

To be useless
Ser un cero a la izquierda

To backslide
Volver a las andadas

Slow but steady
Sin prisa pero sin pausa
¡Contigo pan y cebolla!
The common and very familiar Spanish expression contigo pan y cebolla is used in Spain in a humoristic way to let your significant other know "how deep is your love". The fact that a couple may not have a lot of money is not an obstacle for them to get married and live a happy life as long as they love each other. Bread and onions used to represent two types of food that are available to anyone and people with a certain social and economic status would never indulge in eating them, since they can afford a more varied and healthier diet. The idea of contigo pan y cebolla may be expressed in English with expressions like: with you through thick and thin; If I am with you I do not need anything else; through all the ups and downs; I'll forbear any burden in life being with you.
