This throbbing of the heartbeat

I read a Tweet about Roald Dahl's “Full of Witches”.

I was spending my days wondering how I was going to live my life.
The reason is that I started to feel that my job is monotonous and boring.
Maybe if I grow as a business person, I will be able to do a better job than I am doing now. What's the point of it all, I asked myself.
“Not the long and short of it, but the beating of my heart” and “I'm in my thirties and I'm trying to figure out what I'm going to be.”
Those two words gave me courage.
Maybe I could be whatever I want to be now, too.
I could quit my current job, or I could work at another job.
I could be bored at work, but I could find joy in my personal life.
The only thing that matters is this beating of my heart!
