The approach depends on many factors and differs depending on how much time, money and effort you want to put into the channel. A few more details and background information can improve the quality of answers.
- Is this channel just a hobby or do you want to run it professionally and earn money with it?
- How much time do you want to invest into the project?
- What's your budget if any? For example to outsource creating your corporate design like logo, name and thumbnails.

> How can I create a good thumbnail?

A good thumbnail for a video should look interesting to get the attention of viewers but also faithfully represent the content. You could take inspiration from other channels and make a collection of thumbnails you like and try to identify features that are the reason you find those thumbnails interesting and then create thumbnails in a similar style for example with GIMP.

Since you are already talking to an Open Source AI Assistant you could try Stable Diffusion to come up with some thumbnails and maybe you can generate a few you like and find your style that way.

> How can I create a good name?

A good name should be memorable and reflect the spirit of your channel. You could brainstorm some ideas by writing topics you want to cover and rank them. Try to combine different words (portmanteau). The english word _"smog"_ for example was coined by blending the words _"smoke"_ and _"fog"_. Once I've more details about the kind of channel you want to create you could ask me for some name ideas, maybe you like some of the suggestions or they inspire you to find a name you like.

> How often should I upload?

That's entirely up to you and depends a lot on how much time you want to invest and how long your videos are and how much time is needed to produce those videos. Typically it's more important to try to stick to a regular schedule but if you want to post daily, weekly or once per month is up to you.
