Gary VaynerchukCrushing It!
Every great business owner should be trying to learn from other entrepreneurs. There are people that have been where you are, learnt a lot of lessons themselves and now, are willing to share those stories with you so that you can learn them too.
For me, Gary Vee has always been an inspiration. He's on trend with what's happening, is a proven successful businessman and definitely someone to learn from. If you're wanting to create a strong, scalable brand, I'd highly recommend his book Crushing It! The book covers a lot of great things and key lessons that you'll be able to take forward into your own entrepreneurial journey.
