Why pay for something, when you can get it for free?
Namely- knowledge and information. Is it just me, or are there less DIYers these days?
I’m more inclined to trust someone who isn’t asking me for money, because they aren’t as interested in gaining my patronage. (Naturally, I have no problem with professionals like @Dr_Lawrence, who offer their advice for free online.)
I could pay someone, or use Youtube/Fluther. Either way, I just learned a new way to deal with my control issues, or how to change my car filter, or how to make a birdhouse. There are tons of free resources online and at public libraries. Why bother paying to learn, if I am capable of teaching myself?
