For the first time of selling stocks

For the first time I hold the stocks.
And this is the first time I sold stocks. After keeping the stock of China Bank for one week, I sold them at last, and gained 30 cents.
The reason I hold and sell stocks is that I just want to taste more things, anything you have not tried you do not know detail about it, so I bought and sold stocks.
Next, I may set up a company and run it.
