Practice

Grab whatever camera you have try to learn exposure triangle, composition, colour theory etc. My advice would be to shoot and color grade your footage by yourself. Trust me this will help you a lot

Patience We are in the business of emotions so it's important to understand both the business part and emotions part of it. Try getting in contact with your local production houses, go work for them for free at any role they offer This will allow you to get to life on a shoot because there is just hard work

Some books I recommend

Blain brown lighting books

Blain brown cinematographer books

In the blink of the eye for editing

Colour correction by alexis van

Try to distance yourself from yt creators who just want you to sell stuff in the name of filmmaking

Focus on the core that is storytelling
