There’s no more excuses. If you want to be a writer you can be one. Set up a blog and tweet to it. Share your work.
If you want to be a photographer, you can be one. You have a phone with a good camera and a distribution network in Instagram. Share your work.
You don’t need permission from anyone to do these things.
It all starts in good fun. But then you get good at it. Your main challenge is deciding how professional you want to to be about it.
No one writes books or takes photos and shares it on the web if they don’t have to. Now that you have the toolkit and the audience, do something with it and show people things they haven’t seen before.
Use your work and reach to share a vision.
