Do you have a "to do list" on your mind or on your paper note? It could be the cause of growing age. I need a reminder like a "to do list" to keep myself distant away from distraction. There is an item of study on my everyday list. No matter what kind of study is, just learn something new each day. I am doing this just for keeping myself in a positive station and being young. In the view of my point, studyless makes people grow older quickly. One of my mottos is to keep learning till the end of life. Recently, I added another item on my to do list, make one correction at least here. Not just for the ones who have helped me but also for all the people who are learning Chinese. Helping is always a good way to fulfill happiness and sunshine in our life.
