If you have a day job, but dream of getting out on your own, it all starts with a side hustle. However, there are some common antipatterns in side projects that you should be aware of when you are coming up with ideas (or choosing between them). Side projects fail in predictable ways for reasons that are easy to see if you know what to look for.
Sometimes you just know that a person is on the way out the door. Even when it is more subtle there are signs and indicators that can alert you to the fact that one of your coworkers is looking for greener pastures. Many of these are changes in the normal behavior of your coworker. Indicators are when they do not act as they have or do things they have not previously done.
