IS IT GOOD TO CLARIFY?

i encountered some problem at work today
so instead of keeping silence abt it, i went to seek advice to KILL IT
and then i was very impressed tt senior J could pt out many issues which i did not see when i first prepare the tender
but of course, some of the issues, i did point out to the project officer but she did not want to see it my way and insisted her way
still becoz i cannot get over it so i went to clarify
so after clarifying, i had heaps of stuff to clear tomolo before i proceed with the next step

i think to myself "don't think u did a good job. made a mess out of it. just want to cheong it out"
so ashamed of myself u know
what will ppl think of me............bad job lor, not GOOD JOB!!!
end of the day, is it good to clarify?
i guessed it is bah
more work, but at least i can kun better...........dun u agree?
