personally I think you can.
I love being in the field and wouldn't give it up for the world. that why I started my business. I put myself in the second category as well.
now I've since decided to remain solo, maybe add 1 employee in the future. but before that my plan was to grow, grow, grow. and you know what, in that plan I was going to remain in the field and eventual have someone else sitting in the office doing invoicing, accounts payable, phone calls and going out and giving estimates. I've never wanted to be that guy not doing the actual mowing, trimming, mulching, etc. I'd rather hire someone to do all the office/business side so I can remain in the field.
so yeah I'll gladly admit I'm a landscaper vs a business owner if forced to choose.
