I've got to agree with almost everything Cadetkid said in that last post, including the bit about negativity, because I know I come across that way sometimes.
I just wrote a big long response, twice, then deleted them both, but when it comes right down to it, it's just a job. At some point you're going to whinge about your managers, or the food in the canteen, or the fact you didn't get the sector you wanted. If you're 100% positive through everything you do as an ATC, please let me know what sector you're controlling, so I can avoid it.
