After experimenting with freelancing for a while, I realized that I would prefer to use my abilities to provide free assistance to anyone in need. If I receive a few referrals along the way, that will be sufficient compensation for me because it is less competitive and serves a greater good.
Before you can start freelancing, you need to have a digital skill you can sell to others. It can be writing, graphics design, copywriting, website design animation etc. The more you are good in them the better.
I have been freelancing on and off myself online since around 2012 to help with extra income and it really does help a lot if you have something to offer that people are looking for. I myself have freelanced in the past for forum posting, blog posting and also article writing. If you have basic grammar skills, then looking into something like that is always a good option to help you earn more income. I myself also have in the past used a site called SEOClerks which allows you to offer your services.
