And now to the hustler business and a hustler apparently always being a hustler!
One, your education need not suffer because of a business or two. A vast majority of university students nowadays spend most of their time partying, on social media, downloading and watching the latest movies and series etc. When a smart student starts something on the side, and you seem like one, it is these social stuff that suffers. You will probably be even more focused and organized because you don't have "all the time" like the rest. You can study and work/run a business. People do it every time all over the world. You just need to be disciplined and organized. Ni vile wakenya walikuwa wamezoea kupigia mzazi simu awatumie pesa ya kununua socks!!
Two. Do "University hustlers" become hustlers for life? Yes and No. No because there are those who choose to get employed and live happily ever after. No because there are those who CHOOSE NOT TO GET EMPLOYED. Let me focus on the later category. A proper "University hustler" is not a fellow to wait for graduation and certificates to be out to start applying for jobs. Their brains work over time and they will see numerous business/hustling opportunities long before the graduation day. By the time they are putting on the gown, they will be making much more or on the way to making much more than the fellow who would be interviewing them makes. They totally lose interest in getting employed because they are making multiples of the best offer they could get, work flexible hours and they can see themselves making even much more in the not so distant future.
Now, the fellow who was taken by PricewaterhouseCoopers straight out of Campus as a Graduate Trainee meets them wearing a T Shirt and jeans while he is in a suit and tie (not fully paid for) and feels sorry for them. He compares his Smart Phone to theirs and the fact he is carrying a (company issued) laptop and thinks he is the one who made it. Unknown to him, the T Shirt fellow is probably worth millions, doesn't need to wear a suit and is probably his landlord!
The problem with some salaried Kenyans (not all), they think the guys doing their own thing are suffering or are doing so because they have no option. There is a lady I know who got a First Class and is very good in her field. I wanted to recommend her for a job and she respectfully declined. She didn't even want to know the salary yet it was a company "with a name". And what does she do? She works online!! She started while she was in Campus and because of good ratings, her accounts (two) have the highest possible rating and certain repeat clients request for specific people (including her) to do their jobs. She told me she easily makes upto 15,000/= by noon some days and she actually selectively picks jobs. She could make more if she wanted - pick more jobs, work more hours. She has started farming like you on the side (I guess for the love of it) and even employed people - on the farm, sales etc. but she keeps getting a familiar question "Haujawahi pata kazi?"
Please note: I am not saying between employment and business/hustling there is one that is better than the other one. It depends on very many variables - The individual, goals, plans, type of job/hustle/business, values/perceptions etc. Whatever floats your boat might not be what floats the next guy's boat. I just wanted to counter this perception that Campus Hustlers are forced by circumstances to be perpetual hustlers.
Never count on making a good sale. Have the purchase price be so attractive that even a mediocre sale gives good returns.
