Losses and profits when trading stocks are partly determined...

Losses and profits when trading stocks are partly determined by luck; the other part is determined by personal subjective intentions and perceptions of investment. Perception is unbreakable. If you want to earn money other than your perception, you will often lose money first. Since investing is risky, you have to taste all the results yourself. A good mindset is a process that is easy to say and difficult to do. If you are not greedy in investing, you are also afraid that your wealth will run away from you. If you are greedy, you may get farther and farther away from your wealth. The balance between these is really hard to grasp.
