So is happiness always conditional? If we remove our fear "I will certainly stutter on this letter", then it will make us happy because we are one step closer to fluency but I don't think it works like that. You've learned to stutter "it's my way of speaking and it's a habit" and as long as you believe this, you pull yourself back into the previous mindset. So the question is: if happiness is a conditioning, how can we let it impact us so we go for a fluency mindset?
