I'm not sure any addiction is good Megan.
Definitely some ( like coffee or chocolate) are better than drugs or alcohol.
Life.
I like guns , collect them . Also love cats , or almost any animal, both addictions don't seem to bad . Also addicted to exploration - here or otherwise
passion!!! Passion for love, life, nature, drama, learning, travelling!! Everything
While a "Balance" of anything is the most Healthy way to for people to live their lives . . . "Learning" might be an acceptable addiction as long as it controlled and doesn't pull you away from family.
