It does not matter your age, someone can learn from you. What have you done and then wanted to do more? Our life must serve as an example for others.
It is not big or the small you will do that determines your ability, but it depends on the honesty you will show on your daily activities that qualify your ability. Means, be honest in your work and do the best thing for a good reward.
You must be unique in all your doings. Do not let others question your work and ability of your doings. You can do more on how you have imagined and it can be better than what you have proposed.
Try and do the best of all the time concerning the work you have done previously. Let others ask of your ability and honest work. Avoid laziness in your work but do not work to abuse your ability.
Honour your health and regards the rules of health. Do not abuse yourself through hard work but work sufficiently. You need to be a mirror for others. That is, let others find their fault through your act or performance and then correct themselves. Be honest and do honest work.
Be an example and let others learn from you. Many people have failed to be an example of good works. But you need to be an exceptional, no matter the condition.
Tell the truth and eschew evil. Let others accuse and condemn you about your faithfulness but do not mind them. Stand for the truth and die in it. Consider your actions and makes a difference in comparison.
