General opinion is that a side job is one that supports the main income of an individual, often times perceived as something that brings little money to add to what you make from your day job. If Mr X earns better from a side job when compared to the income from his career option, does the side job still qualify to be called a side job?
Most side jobs are temporary employment that aren't totally dependable; they frequently provide benefits to supplement the main or full-time work, which is always supportive since the full-time job's income is never enough to keep you afloat.
Side jobs usually provide additional money, making saving possible and simple; consequently, having a side job that pays more than the full-time work is a great idea.
I don't think it's completely like that because that's how I feel now for example, I'm doing my core job in an office at the moment and my side job is managing a Chanel on youtube as well as some Crypto trading. And this is not always temporary in my opinion because it still has a long chance especially when dealing with the internet world
