When to quit

The question of when to quit, comes our way in life by many circumstances, we all live in a, if I could only win kind of attitude. I live that way from day to day and I am a beleiver and a Veteran but sometimes its just time to quit, no matter what you do know, the people around you will always weigh your faults no matter how few as greater then your accomplishments. Yes I am whining but I'm tired of trying to be right by my moral beleifs and also be expected to live by everyone elses thoughts and ideas. The Bible says let every man be persuaded in himself, but everyone else will tell you that you are wrong and it doesn't matter what you do someone will disagree. You can do a million good things but the few bad things that have happened in your life, will always outweigh it in their minds. Its like being a veteran doesn't matter because you haven't got a set amount of time. The thought of working for DOD wasn't even enough or not that important and fighting fire for the county or state, is only good if you are still doing it . You can feed thousands and you'll be remembered for the one you didn't feed.  I wish sometimes I could just be me and gain respect for what I am without people always looking for an alternative motive. We as a people always have more hope in the failure of others then in the success of a person , friend or foe.  Well i've been told that  God will remember and I pray that is true, it seems no one else will. They will just judge any negative they can dig up, and if they can't find negative they will create something, well win ,lose, or draw you got to always have a feeling to quit, but I pray someone will look at someone different and look for the hope and know that the Bible says a righteous man falls seven times and gets back up. What is a Veterans when to quit.
