Of course we all want to do teshuva for all our aveiros including this one. But is that why we are on GYE? We are here for the here and now. We want to live as good and wholesome and erlich and respectful and happy and G-d fearing and fulfilling and pleasant lives as we can. We want to be the greatest husbands and fathers as well as being role models for the community. We want our olam hazeh to be one where the Shechina is comfortable in our homes.

Agreed. But for myself I know that the fact that I thought I could never do teshuva meant that I was permanently besmirched and blackened, which is something that makes it harder to fight. One of the most powerful forces in this fight is the positive identity as a fighter that we reach when we start trying to succeed, combined with the identity we hope to reach as we move along. Feeling permanently ruined and defective but "hey it can get worse" is not enough motivation to keep up the fight for long.

This idea is also backed up by numerous Gemaros and Torah sources, that when people feel they can't do teshuva that causes them not to fight and to give up. It's close to impossible to stay motivated with such an attitude. So while I agree with your point, I feel that this is very important as well.
