I tried to talk about this to a friend, but he boldly rebuked me saying that "proving doesn't only come once", he said that "you have to prove yourself all the time".
Several years passed... In my Christian life and now that I've read the gospel, whenever I try to look back at what happened, it reminds me of a certain parable that Jesus Christ taught his apostles. You can read about it here.
If you don't have time to read (which I doubt), let me give you an idea of what it's all about.
Jesus told about workers being hired for a certain amount, say, during an early part of the day. Then, the employer hired more at a later part of the day for the same pay. The early workers started complaining, that they should be paid more because they worked earlier (and probably more).
However, they all agreed to work for a day for the same pay. And so, it is a fair amount that they all received. Here is another good read about the parable.
This has the same practical applications in our daily lives, in work and in school.
Sometimes, we will grow weary and think if it's all worth it. The prophet Isiah wrote that "Even youths grow tired and weary, and young men stumble and fall;but those who hope in the Lord will renew their strength". Besides, "They will soar on wings like eagles; they will run and not grow weary, they will walk and not be faint.". ~ Isiah 40:30-31
Stop living life as if everything is unfair, we all have 24 hours a day. Go out there and prove your worth. Don't prove it once, don't prove it twice, prove it all the time.
