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? IMO, you're right
Q2. On another note, can rich experience be treated as uncountable?
for example, a rich experience vs rich experience. IMO, again, "a rich experience" sounds odd. "an enriching experience" may make more sense, especially if it was just once that you had that experience. If it's more than one (different vets at different times, all of them providing an enriching experience, the drop 'a'.
Thanks in advance.
