To sum up, I think that as your working years increase and your understanding of life deepens, you should keep thinking about three questions:
Is it right for me to be a programmer?
Should I be a programmer for the rest of my life?
What kind of attitude do I have towards programming, is it enough or just keep researching?
最终，明确自己的职业规划，对自己的规划负责并为之努力。
