I like this book a lot. There are a lot of things in the bood that have helped me. Actually, I found many resources online
I especially like the way it helps you to create a detailed plan of action and there are many things you can choose from since different things work for different people. I used to be somewhat narrow minded and dismissed certain things that didn't seem useful to me. But at times when I got stuck, I either went back to things that I already looked at and maybe didn't use properly or looked at the things that I dismissed. Because I kept going and looking, I feel very confident now. There are a few areas where I don't want to feel the anxiety (e.g. Toastmaster) but now I know that I will achieve my goals.
Of course, you'll have to do your part of the work that won't be easy but I'm at a state where I can say that going through the hard things was definitely worth it.
