I once heard someone use this thermometer vs. thermostat analogy in a discussion about attitude and behavior, and it really resonated with me.

In our daily lives, we face situations that feel beyond our control. Some people act like thermometers, merely reflecting their environment—joyful when things are good and discouraged when they aren't. Others function like thermostats, intentionally setting the emotional tone in their lives. The difference between a thermometer and a thermostat reveals an important truth:

To God, age truly is just a number and human construct. His plan for you and your life prevails, despite your age. No matter what limits you see for yourself on this planet, God has the power to overcome them all.

If you’ve been putting off what you know you ought to be doing, make today the day you “plant the tree.” Obey God and plant in faith, according to His wisdom and counsel. The outcome ultimately belongs to Him.

As we work here on earth, we really can take nothing with us. This is not to say that what God calls us to build and create here is without meaning, but we need to remember our priorities, and that God Himself is the source of all beauty, life, and wealth.
