One of my favorite quotes is from anime(One outs) character Tokuchi Toua - a low possibility means it's not zero. I think that this quote encourages people to believe in themselves and try their best to achieve their dreams. Because nothing will happen without our trying so it is better to try and fail than not to try all.
As you can see my handwriting is quite bad. Sometimes even I have hard time understanding it.
A good quote indicating that one should try even when there's a small chance of success.
