I used to operate in an Internet company in Gulou District, Fuzhou , Every day 996, In the face of endless overtime , I'm tired of , He chose to start a business with naked words .
I like drinking milk tea very much , So I want to open a milk tea shop , Do as you say , The next day I began to look for stores on the street , There is a milk tea shop next to the community at home , Look at the , The transfer fee is not expensive , He took over .
In order to save cost , Only the soft fittings such as doorhead and tables and chairs in the store have been replaced , The decoration of the store is still the same . Even so , A meal also cost nearly 12 Ten thousand yuan , Including store rent deposit and store 5 Ten thousand yuan transfer fee .
After opening , In order to attract enough popularity , Made a “ Buy 1 Get 1 FREE ” Opening activities , It's powerful , Attracted a lot of young people . After closing at night , I calculated , Buy one get one free activity, sell one cup to lose 3 Yuan , How can such a big loss be withstood , A week later , They suspended the offer ; After returning to normal prices , Business has plummeted , When it rains , I can only sit in the shop with the clerk in a daze .
Business is good and there is no money to make , Business is bad and there is no money to make . Making money for the landlord every day , It's all nonsense ！
Business is bad , Start trying all kinds of ways
It is said that short videos will help store business improve , So I started publishing short videos every day , But the effect is not good , Each video has less than 1000, For half a month , There is still no video with a reading of 10000 .
It's said that the live broadcast is very popular , Try to make live broadcast and bring goods in the milk tea shop , But the number of people watching each time is less than 10 people , Did 10 God , And gave up completely .
All kinds of ways have been tried , In the end, it didn't bring good changes to the store , Business is still tepid , The daily turnover is less than 2000 element , At the worst 800 element , I can't even earn rent .
Loss after one month 2 Thousands of multivariate , business 3 Months , Compensate 20 ten thousand , Seeing the landlord urge the rent again , Only the transfer information can be posted at the door of the store ,10 Within days 5 Bo people , All feel 5 The transfer fee is too high , Finally, on the eve of rent payment 1 ten thousand Turned out .
The kitchen 3 Spent... Months ago 3 Equipment purchased for 10000 yuan , Finally 1500 Sold to second-hand equipment recyclers at a low price of yuan , In the face of such a result , I just want to say ：“ Reality is far more important than phenomenon , I regret opening a shop ！”
After closing the store , I'm looking for a job again , But think of doing business every day before 996 Low wages , I don't want to deal with people all day , Too tired , I want to learn something technical , OK, change careers ！
Later, some former colleagues and friends said that I could consider learning python, Front end and java Now there are many people engaged in , It may not be very competitive just entering the industry , So I chose python, from 8 Learning begins in June , Studied for half a year , from python Basics 、 front end 、django、flask、 Reptiles 、 Data analysis 、 I've learned everything about machine learning . Also successfully found a favorite development work , Although the salary has not reached the psychological expectation for the time being , But don't worry about the store anymore , Want to come , But it also ended up “ Relaxed ”！
