What should i make my YouTube channel about?

[Chaska]

I have been wanting to make a youtube channel for about 4 years now, I have had 3 gaming channels, 1 tutorial channel and a gaming history channel where i have uploaded 2 videos. I cant do gaming coz my pc is tooo slow and gaming history already exists.
I want my channel to big(10,000 subscribers) so gaming wont work there are just too many channels out there and i am not funny when comparred to someone like pewdiepie or smosh.
things i am good and like doing are:
Playing games, photoshopping and video editing (I am actually pretty good at it), coding and maths.
I want to have an original channel(another channel can be the same but i have to be able to do something different)
please help me thank you!!

If you are good at programming, video and image editing then why don't create some cool tutorials for others related to it. For example- how to do certain kind of effect in Photoshop?, how to perform certain functions in a specific programming language?, or something related to it. Use your skills to help others or shows your creativity to others.

For promotion of your YouTube Channel, you can use social media sites such as Facebook, Twitter and Google+. These are a good source for increasing your YouTube subscribers or viewers.

Make tutorials, think of unique ideas, and most importantly: Do what you enjoy and don't just do things for popularity.
