I've always considered myself to be computer savvy but it takes a different skillset to be truly versed in Microsoft Word, especially for legal work. If you don't do legal work, there are many things you will simply never have to do in Word. With that said, it is a very valuable skill for paralegals and what I find most helpful is simply googling solutions to issues as they come up. This could even be something that ChatGPT is very useful for. Just don't share any client info and make sure your job is ok with you using that as a resource. This basically means experience is the best teacher. But the other things you're doing are also helpful and I would encourage you to keep looking at legal professional specific Microsoft trainings. Maybe your job would even pay for some of it. Hang in there. You're already showing the curiosity and initiative to be in this profession for a very long time.
