You don't need a fancy degree to teach someone. You just need a little expertise in your field and the will to share your knowledge with someone.
Till date, I have involved myself in numerous informal teaching activities by:
- writing articles like this
- explaining a topic to someone in simple terms
- sharing learning materials with friends and colleagues
In fact, just a few minutes ago I wrote up my development studio's mission statement on it's Facebook page.
There, I mentioned that the goal of the studio is not to only make money, it's to help people realise their dreams by either teaching them or providing them with an app development service.
You might be thinking that you're not qualified enough to teach someone something but let me tell you that's 100% unadulterated bullshit.
If you know something well enough, you can explain it to someone else.
There are so many media. You can blog. You can make a video course. The possibilities are unlimited.
Just leave the fear of being a bad teacher behind and go share your knowledge.
