I think it's easy for us to get so stuck in something, that we are very relectant to change. Even when we complain that we don't like the way things are going, we don't always want to switch things up because "what if it starts working?" I recently had a friend help me change my resume since I've been getting very little if any response to what I've been sending out. For the most part, it was more format changing than content. I liked the new look and everything, I was just kind of being lazy to use it. I already had my old one saved to my computer and in my e-mail. It was just "easier" to continue to send that one out. But I finally sucked it up and made the necessary changes to start using the new one. To my surprise, I actually heard back from a job I applied to. Was it the new resume layout? Who's to say? The point is - I wanted a change, I asked for and accepted help and gave the change a try.
I find a lot of people are in the same boat. They don't like the way things are going, they ask for help and feedback and suggestions - and then don't make any changes. Because they're scared, lazy, or want to wait until what they're doing works. How stupid is that? I can't tell you how many people I know have had diet/exercise questions ~ I have given them advice of things that have worked for me ~ and they respond with "well this is what I'm doing so I'm going to stick with that for a while." I'm thinking "hello? Did you not just say that wasn't working? Why would you continue to do what you know isn't working?!" But in the end, I can't change things for you. If you want to continue on doing something you yourself said wasn't doing it for you, that's up to you.
The thing is, most adjustments aren't permanent. Why don't you just try one of the suggestions you've been given and if after a week .... two weeks it doesn't work, then don't do it anymore. What have you got to lose? If you've already conceded that what you are doing isn't working, what will it hurt to try something else? It's certainly a better idea than continuing to complain and ask for advice that you will never take.
