The key to harnessing the power of the Law of Attraction is focus. Whether you focus on what you want or what you don't want, the Law of Attraction brings to you what you focus on because like attracts like. If we keep thinking about what we don't want, we get more of what we don't want. In order for you to get what you want, it is crucial to focus on what you want.
If there are a lot more "don't wants" in your mind than "wants", start by looking at what the want is underneath the "not want". For example, if you don't want to keep going to a job that you hate, shift your focus to wanting a job you will love. If you don't want to be overweight, focus instead on the perfect weight that you want. If you don't want the credit card debt, focus on prosperity and noticing what is abundant in your life.
The more you focus on what you want, the more you will attract what you want to you. You will start doing things a little differently, ideas will come to you, and you will make choices that will be in alignment with what you want. The more you act on inspired thoughts, the faster you will attract what you want. Momentum will build if you consistently focus on your want and keep moving toward it. The stronger your belief and passion, the faster you will get what you want.
If you find it challenging to stay focused and doubts creep in, practice letting go of those thoughts. They are just resistance to the natural flow of abundance and well being that is your birthright. In fact, the only thing between you and all you desire is the resistance you hold on to. Let go and release that resistance, and all your wants will come to you like the floodgates have been opened.
So focus on what you want, and let go of any doubt or fear that comes up about having it. As explored in previous posts, I highly recommend the Sedona Method as a process for releasing resistance. It is super easy and very effective. You are meant to have and experience all you desire in your life. You just have to hone your focus and get out of the way of receiving it.
