Intro
It is important to have a side job or side hustle so you make more money and get more experience. This could be making videos on YouTube or making blogs on Steemit like me. I will focus on freelancing and how to become one. It could even replace your full time job.
Getting the skill needed
It is important you have the skills to do the job. You can get one from your traditional education system or get it from sites like codecademy, Khan Academy or Udemy. You do have to pay with Udemy but it quite cheep you get high-quality courses from there and it is more structured compared to reading blogs and watching YouTube video.
Setting up and getting the job
Then you need to sign up for a site like Feverr or Coinality and look for a job that needs the skills you have and then apply. Make sure you have a good description, profile picture, etc so you look like the best among the other candidate. Also provide evidence that you have the skills and that you are the best person for the job. Here is the guide to being a successful freelancer (focuses on Fiverr but works on any site). Then if the employer likes you, you get hired. Do the job, get paid by the employer and you just completed your first freelancing job. As you do more and more jobs, you shall get more experience which you can use to get more money.
Summary
Freelancer might replace traditional jobs so it is important you hop on the bandwagon first and those who hop on the bandwagon first will see the most benefit from the bandwagon.
