I got this from Bo Sanchez Soulfood Newsletter. This is his explanation about why focusing on your dream is important to your happiness.
“The act of choosing is oxygen for your soul.
Choosing feels good!
I’ve met countless of people who can’t choose. They run their lives on fear. Because they fear others, and what other people say, they let other people run their lives. Their bosses. Their families. Their friends.
That is one miserable way to live.
Happy people create their future. It’s not created for them. They deliberately choose what they want to do and where they want to go.”
