What's one thing that makes you feel fulfilled?

I'd day learning something new.

when people use the things you've built :) how about you?

I think When you are satisfied with your own work and you make your client satisfied. I am Working as a Staff Augmentation Services Manager at https://www.virtuenetz.pk/servic... from the past 3 years and it means a lot to me when my Client say "Ohh! That's exactly what I wanted...Thank you Ariba".

Now, i don't feel it.
