Character does not come by chance. It is not determined by one outburst of temper, one step in the wrong direction. It is the repetition of the act that causes it to become habit, and molds the character either for good or for evil. Right characters can be formed only by persevering, untiring effort, by improving every intrusted talent and capability to the glory of God. Instead of doing this, many allow themselves to drift wherever impulse or circumstances may carry them. This is not because they are lacking in good material, but because they do not realize that in their youth God wants them to do their very best. MYP 163.2
If the youth today would stand as Daniel stood, they must put to the stretch every spiritual nerve and muscle. The Lord does not desire that they shall remain novices. He wishes them to reach the highest point of excellence. He desires them to reach the very highest round of the ladder, that they may step from it into the kingdom of God. MYP 164.1
