I am happy. For no reason. That’s just fine, since reasons can be pulled away beneath your feet like a carpet. There should only be reasons for unhappiness. You can get rid of them.
Reason is overrated anyway, it won’t take you very far and it doesn’t promote happiness on its own. The search for reason behind the unreasonable is actually a source of constant frustration. Sometimes it’s just fine to let go and enjoy life as it comes.
