Mind you, I'm not saying you can get what you want by just thinking about it alone, but do you believe thinking positively somehow boosts you closer to getting what you want?
Yes of course it does. It's not magic though, which is sad.
You develop a positive outlook, you pay more attention to the positive aspects of your life and give less value to the negative. (In your case you are pleased to note an increase in responses and not so worried about not having a concrete job offer on the table
yet) This thought pattern feeds itself, your positive focus sustains your positive outlook. When you feel optimistic you are more likely to energetically apply yourself to tasks (the job hunt), you are more likely to take positive emotional risks (making confident pro-active phone calls/bold statements which sell your assets to an employer)- action which boost your probability of success in your task, and you are more likely to network and socialise successfully (you appear to be a desirable colleague/employee/new friend, other people pass along opportunities and recommend you more freely). With persistence of the positive mindset the goal will be reached and enjoyed.
With a negative attitude the goal may not be reached at all due to debilitating lack of confidence, apathy, lack of ambition. OR it might be reached in just the same time span, but feel like a torturous thousand-year effort getting there and thus not feel like a success or an achievement at all... in very cases of a very negative mindset the fact that a goal was achieved is totally overlooked and the feeling of failure still persists.
In short, it is vital to dream. Visualising getting your needs met or getting what you want is extremely important. Just imagining yourself in this future scenario won't magically make it happen, however, understanding that there is a process you have to go through to get there is key, and positively receiving all your successful milestones along the way - enjoying the fact you are working toward your dream future - is what makes it possible.
