It's true that I had teachers that didn't give up on me, and I was very fortunate to have those teachers, because I often gave them cause to think there was no reason to invest in me.
Es cierto que tuve profesores  que no me dejaron renunciar, y fui muy afortunado  de tenerlos, pues a menudo les di motivos para pensar  que no había razón para invertir en mí.
