The problem for a beginner is that few can afford a mentor, as this will require additional costs to pay for this type of service. For this reason, many beginners use free training programs, the quality of which is not always satisfactory, which ultimately leads to the loss of the deposit.
I believe free programs or mentoring isn't that bad if a person is interested in learning. The internet is full of free resources about almost everything you can think of, I know that there might be limited information in each resource but if someone combines multiple resources and learns from different sources over the internet, they can learn things just as good as a person learns from a good mentor. It's all about having dedication and willpower to learn.
I have seen a lot of people who are self-taught in a lot of things that they do and believe me, you won't believe they have learned everything themselves when you see them doing those things because they have become so efficient in them. So it's all about focusing in the initial stage and then practicing what you learn, whether you have a paid mentor or you are learning from free resources, if you are practicing constantly, you will become perfect in that thing eventually.
