First and foremost "never" is a bloody long time. To the op I side with you, anything can be achieved with enough time and hard work.
To the post about being outclassed on guitar by your drummer, learn from it and don let someone else ruin you love of playing bass. Playing an instrument is no different to any other skill, unfortunately there are some people who are naturally inclined towards it. Usually these talents are picked up early in life and nurtured by our parents/mentors and we continue to improve.
Like most things we do in life, it's an inside (mental) game. What motivates us matters more than anything else. People who can pick up a guitar and play it easily straight away enjoy it and therefore more likely to spend time doing it. If you struggle to pick it up, you are probably going to have to work damn hard and improvement will be slow, therefore more likely to dwell on it and be one discouraged.
Personally I really struggle on bass at times, because I have small hands. But I LOVE playing and want to be an awesome player (currently couldn't be any further from that by the way) so I dedicate time every day to playing and making small improvements. I'm a long way from where I want to be, but at the same time I am a long way from where I started!
