Subsciptions ... which one's are useful and not so useful?

Thanks to all who participate in advance :flowers: Shellee My passion for acting has returned since many years of a 9-5 career in boredom. It has been the best move I have made returning to my passion of performimg. I am fortunate to have created a normal existance in the workplace to help fund my hobby. Which brings me to wonder the usefulness of some website and subscriptions. I am well aware of the need to climb my own ladder in this profession...I don't expect a silver platter... It just would be nice to know where to invest money and where not to. As this to me is more a love of performing not an income. I look at those with experience as great teachers to my craft. The majority of which I am yet to meet, with confidence I know that this is the start of my long venture and would like to know if anyone has any advise on my question???
