After several decades of training people in martial arts, the military, and strength & fitness I have seen some very predictable patterns of behavior in people.
Some have been incredibly rewarding and positive, but some are anything but that.
While no one likes to be called a quitter, people quit good things all the time.

Very few ever have the guts to just admit they are quitting, usually they just start fading away.
- they miss training more frequently
- they always seem to be hurt in some way
- everything else is a priority except training
I could go on, but you get the point.
Don’t be that guy or gal!
