Read countless books, articles, watched youtube channels, videos and read diverse forums on diverse aspects of trading (mostly technical). Much of this had for free, but only a starting point no matter how much time you spend, as it's mostly about forming concepts and ideas in your mind in order to begin asking the right questions about the markets. Spending money might make you more focused, but no guarantees for success.
When you start seeing possibilities in the markets play out, and ask the right questions, can you begin to uncover that 99% of ideas out there are unusable garbage. For you anyway, maybe useful to someone else.
Mentorship, when it happens can be a beautiful thing, but is a happening. You cannot and should not force the flower petals to blossom. It'll happen in it's own God damned time.
