regret.

to me, regretting is the worst feeling.

"if only i did/didn't do this or that, then things would be different now.*SIGH!* "

if you don't wanna feel regretful about anything in the future,
then don't give up on anything now.
especially the things that seem way beyond your reach.
just believe that He believes in you.
and therefore, yesssss, you can.
