Foreword: After getting up this morning, I saw a system notification from the CSDN official assistant. I happened to have nothing to do, so I clicked to share my creative experience.
luming.02 , unknowingly today is the 128th day you have become a creator. To commemorate this day, we have prepared an exclusive surprise for you, and we look forward to your picking it up (valid for only 7 days! )
Opportunity
Talking about the original intention and opportunity to become a creator
Frankly speaking, my original intention was not pure. I didn’t just want to share experiences and exchange technology. Part of the reason was that this thing looked very cool. I thought that if I could have many fans on a certain Internet platform, I would be able to do so. There are related technologies, and I think this is really cool. I feel that this is a very useful and honorable thing.
But as I typed code and learned, I gradually felt the sense of recognition of sharing my skills and experience and being recognized by others. Just like playing a game and fighting BOSS, players gradually upgrade by fighting monsters. Upgrading your equipment, improving your skills and proficiency, and finally defeating the BOSS is of course a very fulfilling thing. It corresponds to your identity as a creator. You learn in the process of creating a blog and slowly improve. For myself, this is just like fighting a BOSS. I slowly feel that the process of improving myself is very fulfilling, and I can clearly feel the joy of improving my own skills. So in this process, I slowly determine myself. Definitely want to be a creator
In the future, creation and sharing will not stop, and most of them will focus on the following aspects:
- Sharing experience in practical projects
- Records in the daily learning process
- Technical communication through articles
- …
Harvest
Speaking of the gains in the process of writing this article, the biggest gains are actually from the technical side. From an ignorant novice to a novice with a little knowledge, I also know a lot more about the computer industry. I also gained a lot of learning methods. I also met many like-minded big guys and learned a lot from them. In short, these gains cannot be expressed in terms of quantity and material. Most of them are personal and all-round. promote
If we want to talk about how much we have gained from the data, it is probably as follows:
Daily life
Slowly, I wrote more and more blogs, shared more and more codes, and created more and more frequently. I gradually realized that creation has become a part of life. Now most of them have classes. If you don’t have classes, think about whether you have any creative ideas and inspirations. If you have them, you can think about how to create and write them. If you don’t have them, you might think about playing games or something. Generally speaking, it’s just a matter of limited time. With the energy of the school, he creates while studying at school.
Achievements
Speaking of the best code I’ve ever written, I don’t seem to have any good code, so here are two programs that can run completely, one is a three-piece chess game, and the other is an address book management system.

Longing
In terms of creative planning, I hope to win the hearts of bloggers within this year, and then publish 30 articles within 3 months.
Of course, my career plan is to enter a big factory and get a decent job and salary. I hope that my gains will be worthy of my efforts, and I hope that I can make unlimited progress.
Tips
- The articles you publish will be displayed in the milestone area. You can also view the anniversary articles of other creators in the area.
- High-quality commemorative articles will receive mysterious rewards.
