1. Learning to heal is only the start (metamagic management and learning to not over heal so as to conserve spell points is part of that.)

2. Learn all the other things you can do too: clerics have some great Crowd Control and offensive damage spells, you can even melee as you start out. Run with a more experienced cleric/FvS (yes two in the group) occasionally while you level, use this time to experiment and learn the non-healing stuff.
