"Getting up...dusting myself off...and trying once again."
I also wanted to say that that's the best thing you do.
A Japanese proverb (and a similar Biblical proverb) says, "Fall down seven times, get up eight." Keep trying, and never give up. If you hit a stumbling block, do like you said - pick yourself up, dust yourself off, and keep on going. Just make sure to keep an eye out for those stumbling blocks and try to steer clear!
