Wow...depression starts to set in for me when I am kinda inactive. I always feel I am stagnant and not progressing like I should no matter what I have achieved.
Adding to the list, set a new goal and get busy. It necessary does not need to be financial or career goals, like @ejamai said a hobby is a way of killing off depression.
Add Steemit to the list, it keeps you busy you forget to get depressed.
I like this..
I think you are right. Thanks for sharing.
