My love for animals, long history of raising animals, and rich experience with vets can be quite useful at XXXXX.
Q1. "MY" is in effect for the series so I do not need "a" in front of "long history" and "rich experience," right?
Q2. On another note, can rich experience be treated as uncountable?
for example, a rich experience vs rich experience.
Thanks in advance.
