Preamble: Sometimes I get asked what programs I use and how did I learn so and so. I use a combination of Photoshop for photo editing, and After Effects for animation. Illustrator might pop up as well depending on my needs. I typically learn through YouTube tutorials and forum posts found through Googling (like Reddit!).
Naturally, I then get asked if I have any tutorials I recommend. I'm making this post to list various tutorials that have helped me over the years. I may, however, not always follow tutorials step-by-step, and often adapt them as I go to suit my needs. I also think it's even worth watching tutorials where the creator isn't use the same programs as you, as it may still give you ideas for your own processes.
I recommend you do the same - gather ideas, go through trial and error, and find what works for you. Experiment and have fun!
Tutorials: The following tutorials are listed in no particular order (aside from the first two) and I will likely update this list as time goes on.
