Tired and cranky seem to go hand in hand. Don't use your bedroom to watch the news or finish up some work from the office. Make that room your haven, a place to relax and escape the day. Have a hot cup of tea, take a warm bath, or read a paperback to help you unwind.
It is challenging to get started. Innovation research will be needed, brainstorming will have to be done and ideas will have to be brought to the forefront. But, there are enormous resources available to everyone in every type of business out there. Books, websites, organizations and many more avenues are available to you.
