You may not able to control every situation and its outcome, but you can control your attitude and how you deal with it.....similar to what I say a lot....if you can't change the situation, the only other thing then that you can change is your attitude.
I don't understand why the fuck this is so hard for people. I mean honestly, what do you have to lose? Is it pride? I don't know about anyone else but I have an incredible amount of respect for people who not only take responsibility for their shitty behavior but actually make an effort to change it.
