Do not be afraid to throw yourself on the Lord! He will not draw back and let you fall! Put your worries aside and throw yourself on him; He will welcome you and heal you.
I urge you to live within your means. One cannot spend more than one earns and remain solvent. I promise you that you will then be happier than you would be if you were constantly worrying about how to make the next payment on nonessential debt.
You're neither right nor wrong because other people agree with you. You're right because your facts are right and your reasoning is right - that's the only thing that makes you right. And if your facts and reasoning are right, you don't have to worry about anybody else.
To study and constantly, is this not a pleasure? To have friends come from far away places, is this not a joy? If people do not recognize your worth, but this does not worry you, are you not a true gentleman?
Don't just sit there and worry. Be proactive. Do something - anything - about what's worrying you so you can gain information, focus and control over the situation. I've suffered a great many catastrophes in my life. Most of them never happened.
