心中充满热情heartfelt and passionate

• 领导干部应设身处地为部属着想，满腔热忱为官兵排忧解难。

  Leading cadres should put themselves in others' shoes and think of their subordinates. They should be passionate about dispelling the worries and difficulties of their soldiers and officers.

• 既然是怀着满腔热忱而来，就不能打击他了，留下吧。

  Since he has come with such heartfelt enthusiasm, one cannot really deal him such a blow. Keep him on.
