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.
