Bruno, your "self" sounds so cool... maybe you wanna convince "it" to join these forums
Thadroe, I can relate to your situation. It feels depressing to know you're wasting so much time on something you don't enjoy. I don't know what your job is, and what your reasons are for not quitting (you probably want to see your own business launch off first), but my solution to this problem (it's actually a patch :P) is to look for accomplishments I can make at work, so that I can boost my confidence, feel more motivated and make a good contribution to my work place.
Some times I write a plan on what I wish to accomplish for work so that I can increase my motivation and be more productive.
Best of luck with your work, and *especially* your own business!
