If you want to direct, fine, but also learn how to do something technical that'll make you more employable as you continue to work towards directing (color grading, editing, DIT, lighting, VFX, something). Everyone here thinks they're a great director and writer. Most people here know they're shit at technical work. Whatever you can do to make you more employable will help.
Be not just willing, but hungry, to network. Unless you make some shit that wins big festivals or goes super viral, you'll need referrals and opportunities from people who like you. Going to school is great for networking, but like the guy above me says, getting your feet wet on sets will probably help you learn the ropes faster. And you can still network.
Have a concrete strategy, be open to learning new things, but also be selective with your time given your finite budget. Not all opportunities are equally worth the commitment.
