Okay, a couple of pointers. I'm a writer (and a yoga teacher).
First, start writing. Build a portfolio, even if it's stuff that you don't publish. That way if someone asks what you've written, you've got something good to show them.
Second, solicit feedback. People can be cruel and brutal, but that's what you need. You need to know your strengths and weaknesses.
Third, publish. Even if it's in a free magazine, publish anywhere where people will let you!
Fourth, find a job that lets you live. Personally, I like to teach yoga, so when things are slow in the writing, that at least is regular so I don't starve to death. It also allows me to fund my travel.
Finally, go ANYWHERE and write about it. Travelling around your home town DOES count, so go places, visit the local sights, do weird things and write about it.
