Sure, but being responsive, cordial and helpful to your customers hasn't started with Gary. It's just a difference between being someone who cares and someone who doesn't (only chasing money). Never outsource your customer support, ever. Today when most companies have crappy support people will appreciate you having even a decent one and will recommend you just based on the fact you took them seriously and treated them like a human being.You don't have to be Gary to be a success with a thank you economy approach.
Reach out and be decent to your clients. Make sure they know you give a damn about them, and you do, because if you don't they will wander from your business.
All of my biggest wins not directly related to hacking Google have been from relationship building, which is basically hard work applied socially. It's not rocket surgery.
Getting a good mentor and socialising with like minded entrepreneurial people is a must, but also hasn't started with Gary. I surely cannot wade through an hour of meaningless dribble to basically learn "don't be a douche-bag and... oh yeah, network a bit and ask for things." Geez.
