I just ran across this quote from Ralph Waldo Emerson, and thought it was well worth sharing:
“Don’t waste your life in doubts and fears: spend yourself on the work before you, well assured that the right performance of this hour’s duties will be the best preparation for the hours or ages that follow it.” ~Ralph Waldo Emerson
Now I just need to stop browsing and get back to physics homework

Thanks for sharing. This site is full of good quotes. I’ll add one from a book i’m currently reading. “whenever you have the choice, don’t just follow where the path leads. Go instead where there is no path and then leave a trail.”
‘Without Optimism, nothing is possible, with it, everything is.’
‘Fortune favors the Brave.’
‘I’d rather get lost than be too afraid to take the ride.’
All gems!
