I will because the feeling of paying someone for a honest day's work and thanking them for a good job is awesome.
Because surprising your employees is sometimes way better than delighting your customers.
I will first understand the industry's in and outs..
I will aim to find an easy insertion point, then slowly wedge the rest of the business in.
I will focus on building a business, not starting a startup.
I guess I will never stop, it's just too much fun =)
