Hello, Zuzana, and Welcome to Steemit.

A life of travelling is great, but there's no place like home. So, your plan to live a "van life" is a great idea.

Also, now that you are on Steemit, you can document your experiences and publish them on this platform. That might attract a large audience or people who might want to follow your tracks.

Below are a few basic points of advice re posting on Steemit.
1 – Longer posts are more lucrative than short posts. If you make a post of 20–30 paragraphs, it's more likely to earn rewards.
2 – Include some photos, images or graphs, to complement the text.
3 – Make sure the text and photos are formatted properly, so that your post looks attractive and appealing.
4 – Be yourself.
5 – Be interesting and informative.
6 – Create quality content. Steemit is intended to be a platform of quality content. (You will see many insignificant posts with meager content and no quality. Most of those of posts [called “shitposts” by Steemit whale Stellabelle] will earn few rewards and soon pass into oblivion.)
7 – Get online and start curating. Read various posts, comment on those posts you find interesting, and upvote those posts. That’s the best way to attract followers.

Hope this helps for now. Good luck, and Full Steem Ahead!
