Rehearse(排练)as much as you can and practice in front of others at every opportunity. Most of all, think positively.

In 1974, the price of petrol in Britain rose by 120 percent; cars became expensive to run and train and bus fares increased. People who hadn't used a bicycle since they were children decided that they would buy bicycles.They discovered that cycling could be enjoyable and cheap.
