For many, Father's Day is a time of celebration, but for others, it can be a time of sadness and grief. 

Rob Kenney knows what it feels like to be on both sides. When he was just fourteen years old, his father left him and his seven siblings, leaving the youngest to fend for themselves. 

Kenney grew up wishing he had someone who could teach him the basics such as how to tie a tie, jump start a car or unclog a drain, as well as succeed in life. But he and his siblings had to figure things out on their own.

"It was tough. It took me a long time to forgive him," Kenney explains. "It was heart-wrenching for a long time. I held it against him. But I am a man of faith and I was able to eventually forgive him."

Now a father himself, Rob decided that he would help people out by providing how-to tips as well as advice. He started a YouTube channel for anyone looking for fatherly advice, and in the course of three months, gained a following of nearly 2.5 million subscribers, with millions of views for his how-to and inspirational videos. 

"I had no idea that it was going to be what it is today," says Kenney. "I am trying to enjoy it. The Lord can give and the Lord can take away. It's fun to just walk around and spread joy." 

Rob recently released a book, Dad, How Do I? Practical "Dadvice" for Everyday Tasks and Successful Living. 

In this book, Rob shares his story of overcoming a difficult childhood with the strength of faith and family, and offers inspiration and hope.

Today on Connections, Rob shares the inspiration behind his YouTube channel, as well as his book and how his faith has helped guide him through all of this.
