Being involved with Blockchain has given me a sense to look 'beyond' the course and see who the teacher is, if they offer support once purchased, how in depth the course work is compared to Youtube videos, and to see if the guide WILL solve the issue I am having.
I recently talked to a game designer and he said he paid a hefty amount for a guide on how to generate large spaces in Unreal Engine and he said the teacher was lacking in detail, didn't have much information in the blueprints on how to recreate, and whatever could be generated wasn't malleable for him to make use of. No support or community was involved with the guide to troubleshoot or brainstorm solutions or ideas.
Buying something thinking it'll solve the issue and receiving random instructions with no description is the worst.
I think researching every aspect of a guide before purchasing is a good piece of advice. Thank you for sharing it! Hopefully the words of wisdom shared in this post will save somebody the frustration of not getting 'exactly' what they paid for.
