I do not know when it started for me, but I confess. I seem to be in a regular habit of hitting a new procedure with both feet moving, without first reading instructions.
The pro’s to not reading instructions are: you make mistakes and learn from them, and when you do read the instructions they make a lot more sense than reading them cold (with no knowledge or practice).
The con’s to not reading instructions are: you waste money, you make mistakes (sometimes more than once), you waste time, and you encounter frustration.
The lesser of the two evils are…what do you think?
And how many times do you jump ahead, bored with instructions, filled with so much anticipation that you cannot wait to start, just to find out via the end result that you needed to read up first?
Inquiring minds (just mine actually) want to know.
