Don't let future troubles worry you. If they must happen, you will face them when they come with the same reason that helps you handle what's in front of you now.
Let not things future trouble thee. For if necessity so require that they come to pass, thou shalt (whensoever that is) be provided for them with the same reason, by which whatsoever is now present, is made both tolerable and acceptable unto thee.
Think about praise for a moment. Consider how many people who were once highly praised are now completely forgotten. Even the people who praised them are long dead. So don't be ashamed when you need help from others. Whatever task you have to complete, think of it like a soldier scaling walls. What if you're injured or have some other problem that prevents you from reaching the top alone, but you could make it with help? Would you give up? Would you approach it with less courage just because you can't do it by yourself?
For as for praise, consider how many who once were much commended, are now already quite forgotten, yea they that commended them, how even they themselves are long since dead and gone. Be not therefore ashamed, whensoever thou must use the help of others. For whatsoever it be that lieth upon thee to effect, thou must propose it unto thyself, as the scaling of walls is unto a soldier. And what if thou through either lameness or some other impediment art not able to reach unto the top of the battlements alone, which with the help of another thou mayst; wilt thou therefore give it over, or go about it with less courage and alacrity, because thou canst not effect it all alone?
