Is digital analyst a stable career in freelancing?

Hi! I am an executive assistant for almost a year na and I got this job sa referral lang ng kaibigan and direct client but the thing is I dont feel like growing. I did not experience to make a customized resume for this job, and hindi ko rin nararanasan yung magbook ng flight para sa boss ko. Very random pero my point is admin tasks and its not fulfilling for me. I want something na macha-challenge ako and make sure na yung aaralin ko ay worth it.

Do you think po worth it sya?? sa salary? sa paid courses??
