Yes , the law of attraction does work because what you transmit out to the universe is what you are going to get in return. If you transmit negative thoughts out then you will attract negative things back to you. If positive thoughts then you will attract positive things back. Your thoughts become things. When you think good thoughts you manifest then insides and out for the best. Our life will start to process smoothly by applying the law of attraction to make it work for us by transforming of our thoughts to become the things we dream of and always wanted to have.
The power of imagination is amazing , what we dream and desire will happen if we could change our conscious mindset to think positively and tell ourselves we can be successful and rich, we put these thoughts constantly to our subconscious mind and let it work for us. Our subconscious mind does not reason or question. Is like our willing servant constantly out picturing in our world whatever we put into it. If you give it the thought you are always sick, useless, poor and ugly or that the world is horrid and nobody loves you or care about you or you are unlucky all the time, no good fortune will smile on you then your subconscious will go to work on all your negative thoughts and make those thoughts happen.
In order to make the law of attraction works on you, you need to change your mindset right away from negative to positive in order to attract good things to enter your life. To change your subconscious thinking, work on your conscious mind to see things differently and think positive thoughts to attract what you need and then program them into your subconscious to allow it to happen. Tell yourself you are powerful, magnificent being living in an abundant universe that is ready and willing to richly provide all your desires and dream to come true. keep telling yourself that everything in the universe is for you. There is no opposition towards your desire for good things and use the laws of the universe to open your heart to gratefully receive what is given to you.
Positive energy is stronger than negative so it wont take long for you to see a shift in your outer affairs if you take some time each day to relax and close your eyes and reprogram your subconscious mind. Let your subconscious mind to be in charge to think all good things will come to you and you only attract the good.
