Not that I have already obtained all this, or have already arrived at my goal, but I press on to take hold of that for which Christ Jesus took hold of me. Brothers and sisters, I do not consider myself yet to have taken hold of it. But one thing I do: Forgetting what is behind and straining toward what is ahead, I press ontoward the goal to win the prize for which God has called me heavenward in Christ Jesus. ~ Philippians 3: 12-14
Happy people usually have one thing in common, they continue to pursue their goals of knowing more about God and serving others.
If we set worthwhile goals that we care deeply about, there isn't much we won't do to reach them... they magnetically draw us.
Stay focused on the prize of Christ! Make your goals hard, but worthwhile. Stretch yourself to grow every single day and you'll surely find a depth of happiness that will flow effortlessly out of you.
When we grow, we find happiness.
