The extra money we made in those years

 

Maybe the children's shoes all see that there are many great gods in the garden , Making money is quick and easy . Here we discuss how to force programmers to increase their income . image xiaotie ah 、 Lucky day, how did these elders do it ？ Have you ever thought about ！ Of course, I am also one of those who force the public , I haven't reached that level yet , Let me make a simple analysis . Then share the recent 5、1 During this period, I experienced a technical emergency , Share your personal experiences .

There is no shortcut to success , Because of the specialty , So excellent ！

1、 I have known a truth about software for many years ： Demand is very valuable , Business is valuable .

For example, I used to work as a hotel management system 、 Food and beverage management system 、 Sauna cashier system, etc , These traditional management software, which are relatively early in domestic informatization . These software can make Beijing zhongruan 、 Taineng 、 Hangzhou Xihu software and other listed companies , There are also numerous small and medium-sized software workshops . Therefore, professional management software must reflect the advanced management concept of that industry 、 Realize advanced management methods , It can improve the revenue of customers , Improve customer management . So demand is very valuable , Business is valuable . The tragedy is , I didn't get into the big company that made these systems , When I joined the industry, the company was just a workshop . So it's sad . But because I have worked in this industry for several years , Accumulated some contacts , I changed my job later because I was familiar with some needs of this industry 、 Business , Found the project manager 、 The position of product manager . So you don't have to stare at the latest technology , There are specialized skills . When you are the most professional and famous in a certain field, you will succeed .xiaotie It is a leading figure in the graphic industry , Jiri is an expert in authority , There are also medical services like Lao Wei HIS Aspect 、 Enterprise level rapid development platform and other fields ...

An interesting phenomenon , It's also a programmer ：

Some people are half dead , You can't make much money in a month . Some people can easily rely on their own unique skills , A dull voice makes a fortune , The key is still time to find sister paper .

I can only marvel at this phenomenon , Why are people so different from each other ！ It's not scientific ！%……&%￥###

2、 Opportunities are important , Networking is important . You have to write a blog , Read more about niuren's blog .

Subscribe to the excellent blog of the garden rss The habit of visiting the garden in recent years has increased my knowledge , Broaden your horizons , I also got to know some big cows . It is hard to force the farmers to develop well , We must focus on building our own circle . Yes , circle ！ Don't you see that the headhunters come to find them when they change jobs , Successful job hopping of code farmers is recommended by friends , Similarly, most of the extra cash is introduced by friends in their own circles , Or people read your blog and find you . Smart businesses have learned microblog marketing , Manon, you have to write a blog , You can also achieve blog marketing . Brother Jiri's words awakened the dreamer ： I have been blogging these years , It increases every year 10 Ten thousand income ！ Of course I'm not looking for a cigarette here , Money worship . A yard farmer cannot support his family , What a hero . You didn't buy a house or a car in China , You don't get respect ！

3、 A personal sharing of technical assistance .

Before May Day , There is a handsome man ： Shandong Rizhao is a family planning software developer . By reading my blog , I think I can solve the problem of bar code printing , adopt QQ Ask me to add him . He said he could pay for my help . First, he was added , Then I assisted remotely , After writing a piece of code, the bar code printer responded , But the typed items are blank . But that thing needs a lot of debugging , The manufacturer provided SDK There is only a VB and Delphi、VFP Waiting . No, C# Of . I'm using GDI+ To test , Skip the use of manufacturers SDK The way to . But it proved not , Then there is only one Delphi Of DEMO Turn into C# A way out . I said I had to debug many times , No printer . Brother Li said nothing , I ordered a printer online , The next day it was . Brother Li always asks how much it is , I have not answered him out of interest in research , I say it's free if it's simple . It took me a day to finish it . Before informing brother li , He QQ Left a message and sent me some thoughts , I wipe , Shandong lige is so forthright ！ Brother Li's thank-you gift is a Taiwan TV 4 Nuclear tablet ！ value 1300 many ！ It is estimated that brother Li is looking at me to talk about your photos and found that he has been learning Android development recently . No plan, no truth , The picture above shows the following ！
