People love being in a place which has energy and vitality.
The way to pump up your workplace is by setting an example, if you really LOVE being at work and can duplicate that enthusiasm in colleagues then you are half way there.
I say half way because it takes more to KEEP that energy on a long term basis.
Take a look at the fish market guys at the famous Pike Place, Seattle. Now, selling fish is not the most glamourous way to earn a living but these guys go over and above the norm, to make every visitor love being there as much as they do. Look it up on video and watch their energy at work, then try and do the same at your venue. Imagine how our world would be if a few more places were like Pike Place Fish Market!
