Somehow I feel we have the same issue. I am a multitasker, I do a lot of things at a time, and because of that no major improvement. Worse of all, because of the workload I end up not doing any of it.
The changes I am supposed to see end up not showing forth because my mind is not set.
I wrote a post similar to this some days ago. feel free to check it here.
hope you don't feel I am using this as an opportunity to promote my post
I would love to read your story and version. Thanks for sharing it with me and others who read this post too!
Try switching up and doing one at a time to see which gives you more results.
