Our best is all we can ever do....

.....And how do we do that? Well, we certainly don't achieve it by worrying about whether we could be doing better. When we try too hard, we spoil things. We create unnecessary complications. We reopen wounds that are best left alone and given time to heal. When you want to solve a particular problem to the highest possible standard, you still need to remember where to show respect and draw the line.

Always remember the do as you would be done by ethos.  A few minutes of careful thought are worth hours of aimless effort.

If you don't have time to do it right you must have time to do it again.
