I have a positive attitude, even with boring tasks, I still get the job done./or I never complain.

How can I phrase this into a more professional way? Thanks.

#1. Learn to recognize and fix run-ons.

#2. Use better words. Using "boring" and other words like that are typical of middle school students. You don't want to sound like a middle-schooler!

#3. Avoid cliches. How can you rephrase these?
... positive attitude ...
... get the job done ...
... never complain ... (really? never??)
