Not easy.

My tips:

Find communities theme you like.
Make good posts into communities.
Good writing
Good pics
Make friends and have followers.
Earn upvotes.

Also, you earn rewards for curation good posts.

Copy paste content are not good. Be creative.

Keep in mind that you need steem power. Configure your posts to 100% power. And power up your steem to steem power

When good amount. Power down to steem and trade it for BTC or fiat money.

Good luck
