CVs, Cover letters, job application for newbees

So.. any advice on what the hell to put down on your CV or Cover letter? Especially if you have no work experience and you're a downright rookie. What do you do? Coz i have no clue. And i find it intimidating.

Which leads to my second question.

What was your first time like? When you had to apply? Were you this intimidated or is it just me? 😅😑
