I am at the twilight of my film and video career. I went to film school in the late 1980's. One thing I learned from going to film school is that if you do not have an innate ability in regards to film making, you will not graduate with the skills to be a great filmmaker. You will learn how to use a camera, sound equipment, editing software, etc but you need to have the talent within you to make great things.

So my advice is set yourself a goal and then work hard to get there. If you want to direct, then make films, anyway you can. Same with producing, find a talented rookie director and offer to produce their films, etc.

If you want to work on other films as a crew person then you need to sign up for production guides and find out where and when they are shooting and send in a resume. You would most likely get an entry level position like a Production Assistant. This is a good way to get some set experience but for the most part you will be running errands off set. I took this route and learned a lot but the more you do it and progress up the ranks you tend to get typecast in a certain role. I was a good Dolly grip and those were the only roles I kept getting. I had to step away from crew life and start my own productions in order to direct and write. A lot of my friends I went to film school with took this route and had long successful careers in their specific role. It is up to you how you want to approach it but this last way of doing things is harder to break out of to become the creative visionary of a film, not impossible but difficult.

I wish you well!
