Investing time, energy, matter, and money in a goal(s). All goals require some effort and most worthwhile goals usually require much effort. The more effort you use the more time, energy, matter, and money you use. Without effort you are doomed to stagnate in a casual existence getting no place fast and just killing precious time.
Many goals are achieved primarily because of a persistent encouragement or (nurturing and/or protection) and/or motivation by others.
Enthusiasm is a very intense desire for doing something and intense desire is helpful in goal(s) achievement.
Excellence in a goal is frequently desirable and is a standard of perfection in (a characteristic(s) and/or an activity(s)) and/or an object(s). Without excellence mediocrity is frequently your destiny.
