The law of attraction says that whatever you think, whatever you take influence in, your future yields. If you absorb positive energies, your life will prosper. Instead, if you absorb negative energies, your life will be miserable. You are the decider of your destiny. So, don't look back and regret what happened in your life. Don't weep over spilled milk. It is of no use. Instead, fill your mind with positive thoughts about the future.
You will have a happy and contended life. Start thinking that your life will start rewarding you, it will happen that way. Because you will improve only if you have good thoughts.
