Hello everyone, I am Xiaomeng!
I've been so busy lately, with family on the one hand and work on the other.
In the early days, the child had tenosynovitis in his fingers and had a minor operation. I went to many hospitals, and finally confirmed that the minor operation was performed at the Women and Children's Hospital, and it went smoothly.
The moment I saw the child pushed out of the operating room, I really couldn't hold back. This may be the first time in recent years that I cried.
The last time I cried was when Grandpa left.
The child was very strong and cried only once. The child who was undergoing the same operation next to him kept crying.
The more obedient the child was, the more uncomfortable I felt.
During the day, I have been going back and forth with the surgery procedures, and there are 2 customers who are developing in the middle, and they are also very anxious. Let me explain that the system will give it to you tomorrow.
Fortunately, Party A is reasonable!
The child slept very late at night, I coded in the hospital corridor, and stayed up all night to finish the development of the three modules! The nurse came to round the room and asked me:
It's half past three, why don't you go to sleep?
In the world of adults, nothing is easy.
Later, after the child was discharged from the hospital, my dad came to take care of it, and then I devoted myself to the development, and then developed a lot of projects with my friends!
These little friends are all the little friends who entered the previous private life VIP, and it is better to have fun alone than to have fun together! I hope to help some small partners earn more. Some friends have very good skills, but they don't know how to cash them out. What a pity!
We will continue to develop more projects, and some small partners have already taken off:
There are a lot of fans in front of me, the technology is very good, but they don't understand the essence of business, and they have martial arts, which is useless. Brought some friends, they did really well!
The direction is right, get twice the result with half the effort! A buddy did it:
His next steps:

There are also a few other small partners who have done a good job, so I won’t take screenshots one by one, let’s see our results later!
But this recruitment requires technical experience. If you don’t have more than 2 years of technical experience and want to learn, you can work hard to learn technology first:
This is a great era, stop complaining about PUA in the workplace, programmers are 35 years old, why a certain skin can make hundreds of W a year on a planet, why a software company can get hundreds of W a year, you have to find the right direction!
Anyone can learn, imitate, and execute!
We must improve our learning ability and execution ability!
I have worked on a large number of projects, up to seven figures. So as long as the channel is right, the developed project will be fine. The income must be nice.
Of course I have another idea:
In the future, we will share projects, so that we can be stronger and go further! Now there are several small partners who have developed 10 systems. If there are 10 people, there will be 100 systems.
Now I have accumulated 10,000 sets in my hand, so I develop so fast! Many are packaged!
Everyone huddled together, and it was so cool! A group of people can go further!
Of course, I will also give you some of my things to operate my things and make money, because my own energy is really limited. For example, websites, official accounts, and small programs are all there, which is really a waste!
Come for an interview!
Of course, you can communicate at any time about the future of programmers. Which is better, technology or management?
Is it more fragrant to do self-media or private development as a side job?
In short, everyone should plan well in advance, so as to avoid the situation of no income even if they are laid off.
Work is not the whole of life, work is just a better life.
I am Xiaomeng, a programmer. Code words are not easy, welcome to like and follow, thank you! You can also contact me below!
