如果每天骑自行车可以让你更健康，为什么不承诺每天坚持骑车，过上更健康的生活呢？

If cycling each day can make you healthier, why not commit yourself to it and have a better life?

为什么不承诺？害怕失败，害怕受伤，害怕选错人，害怕负责任，因为父母失败的婚姻而害怕。

Why not commit? Fear of failure, fear to get hurt, fear to choice to wrong person, fear to take the responsibility, fear due to parent's marriage failure.
