My first idea is to show up every day make posts daily, and grow your account since it will help a lot through curation rewards.
if you have some more funds, maybe try to join any liquidity pool on the diesel pool, so that you can earn from the rewards, and then invest back either into the pool or to hive power.
some games might gives you a good return, but I am not a gamer, so I couldn't say too much about this path.
