While 'pasatiempo' is the standard word for 'hobby' in most Spanish‑speaking countries, many younger speakers also use the borrowed English word 'hobby'. Both are correct, but 'pasatiempo' sounds a bit more formal. Remember that adjectives like 'principal' normally follow the noun, unlike English where they precede it.
