Painting - Primer for Interior Trim?

I just finished painting a hallway with several doors and it turned out fabulous! I have only been in my new house for a year and have just primed the trimwork, but am not sure when/if I'm going to get around to painting it all. My question is pretty simple. The white primer looks great on the trim and I'm wondering if there is any reason I need to re-do all of it with paint. Is primer enough?

Thanks!

primer and paint are 2 different anamals otherwise why paint.

Priming:

priming is necessary to ensure adhesion, stain blocking and sheen or gloss uniformity
prime all surfaces: use a stain blocking primer that is recommended for interior use; choose from:
latex stain blocking primer: excellent for general use, good adhesion, blocks most stains, superior long term adhesion and flexibility; easiest to use and lowest odor
alcohol-based (shellac based) stain blocking primer: maximum adhesion and stain blocking; moderate odor upon application, requires alcohol clean-up; quick drying; use with ample ventilation
oil-based (alkyd): superior adhesion and stain blocking; high odor upon application; use with ample ventilation; use if oil-based paint is to be applied
do not use PVA latex wall primer for this
do not leave a primer unpainted
c. Painting:

use top-of-the-line interior latex or oil-based paint in flat, satin, semi-gloss or gloss finish, depending on appearance desired
oil-based will provide greater hardness, but may yellow, and will be prone to crack with time
satin, semigloss and gloss paints will resist dirt and handprints better than flat finish
