How much time should I invest into post processing photos

Hello everyone, I’m relatively new to photography and I’ve just been trying to learn through taking pictures of things I enjoy. I’m shooting with an old Nikon camera and nikkor 50-300mm lens mostly doing outdoor stuff like nature and sports photography. As I’ve been experimenting and seeing what .raw photos look like from different circumstances, I want to learn more about how much effort I should put into learning a post processing software. I’ve been using the apple photos app to make changes to pictures and I’ve gotten relatively decent results, I feel like it’s allowed me to change the basic parts a pictures color enough that it meets my vision. I’ve also been experimenting with some free softwares like rawtherapee and I’ve been really struggling to get results, but I know it’s because I just don’t know enough about the software. With that being said, is my time better spent taking more pictures or doing more post processing?
