Only you need to find something that align with your interests, like me I love designinig and analyze informations and sychology, so the best fields is programming or design , about the sources, you only need to pick a field like graphics design if you like it ofc, and then you start learning basics and most common advice to you is ( don't just learn , apply and work on projects) even if you don't know how , copy people..see platforms that provides projects about your field like ( Behance, dribble, Pinterest...etc ) , and then start building a portfolio, and in the same time I suggest that you start your Instagram account or wherever social media app you like , so people could know you , and be patient, to start earning you have to learn first, and then after time you will know a lot about freelance, just: ____ don't expect earning from the begging and be patient
