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 agree with this because it is what I am doing right now in addition to my fulltime job, which is really not enough, but I have seen a lot of people who have found that their side jobs are bringing in more money, and as a result, they have decided to quit their fulltime jobs and devote their time fulltime to their side jobs, a good example of this is running a business, which is why you have a full time job and a side job. I have a lot of friends who quit their jobs to devote their time and energy to their businesses, and they have become extremely successful as a result.
