There’s gonna be one speed… mine. If you can’t keep up, don’t step up. — The Chronicles of Riddick

There have to be standards.  If you cater to the lowest common denominator, you take away a lot of opportunity for success.  Yes, that means that some people are going to have to pull themselves up to the standard, and for some it will be very difficult to do so.  But the alternative is to hold everyone back to make life easier for a few.  This doesn’t mean you have to be a jerk.  It means that you have to set a standard, talk with your people about what that means, both as a group and individually, and give them the tools, knowledge, and time to meet that standard.

It also means you will meet and exceed that standard on day number one.  Nothing kills motivation quicker than hypocracy, and if you can’t look yourself in the mirror and say “I ask nothing of my people that I don’t demand from myself”, then you’re doing it wrong.
