Hi @altherion :)
Thank you so much for reesteming this post and also for taking the time to read and comment.
What's your opinion on focusing specifically on being happy?
I completely share your opinion; as I believe that when people actually focus on being happy, or chase that state of existence they often do through nurturing emotions that aren't necessarily positive. For example, people crave for things they don't have, become attached to what they do have, and grow afraid of suffering. All this, ultimately, builds a permanent state of anxiety. This is when, I think, like you said, it becomes a counterproductive endeavor.
All the best to you :)
