Briefly put, yes. Here’s a post from
Of course, if happiness just jumps out at you, relax and enjoy. but if it doesn’t, go get some. If you’re depressed, please remember that your depression will give you messages like “It won’t work,” or “why bother.” Instead of acceding to the negative messages, take an evidence based approach– try doing things anyway. I went through a period of serious depression in my early 20’s and had good success with this approach, which at the time I thought of as distracting myself from being depressed. Well, it worked– when I went and did things, I frequently forgot to be depressed. I might have gotten depressed again when I went back to ruminating about all the bad things in my life– and there were several– but in the meanwhile, I really wasn’t depressed. so I can say from experience that it helps to do this stuff. does it make you “all better?” Maybe, but probably not. Does it make you feel better for awhile. Yes, definitely.
Of course, if you’re not depressed, doing this stuff can take you from neutral to happy, or from happy to happier. Is there someone who doesn’t want that? I don’t know anyone like that.
