growing older is not necessarily growing wiser

I wonder why life gets progressively difficult as I get older. Somehow, I thought the older one got, the more wisdom one acquired. Here, I find myself woefully ignorant to answer life’s questions. They’re usually about the mundane and ordinary but I can get it complicated till the question becomes a complicated problem, seemingly larger than life. In reality, it doesn’t even actually exist in the real world. It’s all in the mind, that wily, indescribable framework through which all my feelings originate and play their course.
