When I turn on my hot water it takes anywhere from 15 seconds to a minute to heat up out of any faucet or shower. Does anyone know of anything I can do to help this. I'm tired of wasting water just to sit there and wait for the hot water. Thanks.

Between one-quarter of a minute to a full minute? Consider yourself lucky. It takes at least two minutes for me to get warm water at my kitchen sink. :wall:
Depending on what your cost is for water and if the sewer charge is based on the water consumption you may find that wasting the water down the drain is the most economically advantageous route.
There are pumps that can be installed that will recirculate the cooled water in the hot water piping back to the cold water piping and there are pumps that will recirculate the water back to the water heater. Some require only minimum repiping and some require a new pipe from each faucet back to the water heater. All of them will consume energy to operate the pump and all of them will waste energy from the loss of heat in the piping during periods of non-use.
The first step is to thoroughly insulate the existing hot water piping from the heater to the faucet.

Pretty much what furd said. The time you spend with the water running before it gets hot is the time it takes to displace the volume of cool water sitting in the pipes and heat the pipes.
A hot water recirculation pump is an option, though it'll require a parallel run of copper to each point of use and cost energy to operate. Another option might be a small point-of-use heater located strategically near or under sinks. That last option is probably less viable for the tub/shower.
