Only those who will risk going too far can possibly find out how far one can go.
~~ T.S. Eliot ~~
Make an effort today -- to talk to that person who no one else will talk to, to solve that problem that has been plaguing you for so long, to fix that household repair item once and for all, etc. Trying will take you a long way today... perhaps even all the way to success. So even if your heart isn't one hundred percent in it, you should give it a go today.
If you always shy away from things that make you uncomfortable or intimidate you, you will never go as far as you could.
