He revealed that building a successful business requires focus.

"One thing that has kept me going through my entrepreneurial journey has been resilience. I have faced rejection multiple times but that has enabled me to build toughness, patience and confidence.

"When you develop a business, you must focus and be a master of it, if at all you want it to succeed. You will face rejection but that doesn’t always mean you’re failing. Stay the course and don’t quit. #AskKirubi," his post read.
