phlebotomist as first job

wala na kasing vacant position for mt kaya ang inoffer sa akin is phlebo. it will be my first job if ever. ask ko lang if mahihirapan akong mahire as rmt if ever. plano ko kasi sana if ever after 6 months wala pa rin vacant position, maghahanap na ako sa ibang lab/hospi. or should i ensure na rmt yung first job ko? planning din kasi to go abroad. tyia
