We all get stuck. You are not alone on that. Consider not looking for reasons to be happy. What I mean is BE happy without any reason. Use the reasons to add to your happiness. It's what you bring to these things u enjoy. Be alert, pay attention.
Someone told me to "stop striving and start arriving."!
Wow. That's some darn good advice.
Though, I personally am still stuck on the be happy without any reason. I don't think I've achieved that yet.
