Welcome to Steemit @niels0317
From the warning goodbot gave you it seems you are still trying to figure things out here on Steemit, that is not strange i was once like you.
I am starting something tomorrow that will be of great help to you.
I am starting a series in my blog called Humans Of Steemit where Steemians share their journey to growth on Steemit, i believe it will be of great value to you since you are new to Steemit.
