I’d say your most needed essentials are desire, willingness to learn and patience. The tools and supplies are easy to come by and easy to replenish but when frustration hits ( and it will)… press on. BTW- Welcome. You have already discovered the last essential in my book and that is this forum. Use it, get to know the other users. Read every post, past and closed. Make notes and use the book mark. And always feel free to ask questions.
