The only way up is down

If the only way to learn is to fall
why should i fear falling?
it is painful but i'll get numb with it
i have been watching my step every time i walk just not to lose my footing
that's why i never learn

But
today i stumbled.....hard
i hurt but i learnt
i shan't blame luck for betraying me
coz only an idiot would count on luck
And
i shall rise above
next time when i trip i shall stand up quicker than now

i shall be perished if i ever let you slip my mind again
