Be grateful, the more you count your blessings & those of others, the more you will receive. A great app for this is Gratitude Diary.
When we are in a state of gratitude we attract great things into our lives. Also, the more you give, the more you get. I'm currently reading 'The Power of Intention' by Dr. Wayne W Dryer, I encourage you to read it since it holds so many key factors to living a positive life :)
