7 benefits of negative thinking: 1. It will keep you from missing failed opportunities. 2. Helps you to wait for the right timing to do something uncomfortable. You can put off so many things. 3. Helps you to concentrate on all the obstacles of life. 4. You won't waste your time doing things like growing yourself. 5. Open your eyes to others' ulterior motives. You will be able to read their minds. You will be able to develop mental fences that keep others out. 6. You won't need to be burdened by obtaining lasting happiness or fulfillment because you will be so drained. 7. Help you have trouble accepting or respecting others, since you don't accept or respect yourself.
