I don't ever recall simply taking and following another writer's advice and then having it turn out bad.
I have learned many things from reading Hubs that offer tips and suggestions as well as from the HubPages' Learning Center.
A year ago I took an online travel writing course taught by professional freelance writer and a class consisting of both aspiring writers as well as some like me who had done some publishing but were looking to learn more. Our assignments were critiqued by both the instructor and each other and I received a number of tips on my work as well as sharing my comments on writing by others in the course.
In each case I consider every tip and piece of advice I receive and if I feel it is of value and would help my overall style of writing I begin to think about it as I write and begin to incorporate it in my writing.
While most of the tips and advice I have decided to use in my writing have had positive results, I can't think of any that have been "really bad". Some have not worked out as planned but, with over 600 published Hubs, I feel I can afford to experiment a bit in my writing and judge the value of the tip or piece of advice used based upon how well the particular Hub does in terms of traffic generated, ranking and what readers point out in the comments.
