I don’t think certain doors, in my early career, would have been open to me had I not had a formal education. Now, no one asks, as I have a track record. In fact, I don’t even have a portfolio – it’s been on my New Years resolution list for the last 20 years! This year, I may just get around to it, if for no other reason as a record of the stuff I’ve done.
I think it is possible without a degree, but I think you’d need to be mentored by getting an entry level position in a company and learning that way. I don’t think Google and youtube will cut it, unless you are happy to scratch around with the bottom-feeders. You’d probably need a day job to pay the bills though.
It is tough and there is a huge amount of competition, especially at the entry level end. Design became the new black, the new rock n roll at one point. Probably because everyone thought it was a cool career and easy to get into. It’s not. Well, it depends at what level. You want to be a chef, you can probably get a job flipping burgers easy enough and call yourself a chef, but if you want to be head chef at the Savoy, you are going to have to know what you are doing, have learned your craft and put in the hard yards to prove yourself – and, of course, have had the requisite talent in the first place.
i am not saying this to put you off. I still think there is a good living to be made, but you have to earn it – and free videos and a couple of tutorials are not the way to earn your stripes. If you try to do it the easy way, you’ll never get near the plum jobs. I would never employ someone that hadn’t proved their commitment to the job. Even having a good portfolio is not enough. I would want to know you could deliver the goods with a 24-hour deadline and under pressure.
Sorry if that sounds negative, but of what other professional career would you ever ask the question, can I learn on Google and practice professionally? Architect? Lawyer? Doctor? Design has become devalued by the kids with a laptop and Canva, but it requires the same dedication and commitment to get good at it as any of the aforementioned professions.
Try posting some of your work here to get honest (if, perhaps, brutally so) critiques. There are enough time-served, experienced,, knowledgable designers around her who are always willing to help out.
Good luck.
