There are probably a few different ways to translate that into Spanish, and I cannot find any particular mistakes with your translation. However, here is how I have just translated (based on how I learned Spanish):
- No tengo gusto de despertar para la escuela porque tengo que tomar un baño, vestirse, lavarse el pelo, y de comer el desayuno en menos de 30 minutos.
That probably seems strange to you, but it is how I learned Spanish. Where is your Spanish teacher from? My teachers were from Spain itself, but yours might be South American (?).
