Really? I have the same addictions, adrenaline, steemit and eat.
The adrenaline of riding a motorcycle, extreme adventures are the best. Steemit started for me in January of this year, now I spend every day thinking about my next publication. Eat always has been my addiction but not fattening, I still think the same 65 kg (143 pounds)

Sometimes everything starts as a challenge, being the best in what I propose but ends up becoming an addiction.

I think it's not wrong, wanting to be the best at something, should be the purpose of all. @anomadsoul
