Always keep an eye on new trends and adapt as necessary, but if it ain't broke, don't fix it.
That's the best advice for a long time.
Many things change but the fundamentals definitely do not and that applies to all aspects of a business.
If your site is doing well be very wary of change unless you have identified 100% what is good about it. Make changes and you risk inadvertently altering something which is fundamentally correct.
