One thing that will absolutely guarantee you failure in looking for a good wife is giving a rat's ass what women's opinions are about basically anything. The reality is that self-confidence and forward momentum in your own life will vastly outweigh anything else a woman complains about when she thinks about what 'turns her off'. The best piece of advice I was ever given with regards to women is 'Don't listen to what they say, watch what they do.'

Women are plastic by nature; they will mould to you far more than you will mould to them. Changing yourself to suit another's tastes is womanly behaviour, hence it will lose you favour with women quicker than almost anything else. That's not to say you won't have to make changes when you marry a woman, because that's the nature of bringing two imperfect people together under one roof.
