To win consistently is very hard .
It really is a thing of 'willpower' and having a clear plan and mindset..
The problem that applies to nearly all players is, that being online your mind wanders to other things, such as checking emails or looking at sport or any other form of media (facebook/twits)
To play and win consistently at cash games is set targets ie: If your sit down is $20 playto +$40 then leave .
Don't feel any conscience about 'hit n run' many players do it and so should you ..
As for tournaments, thats different, but more of a social pleasure game .Again i think you need a plan as to how you approach tournaments but in those you shouldn't think about winning until you're passed the 'bubble' and then, use your skill to make the final tables ..
good post Dobie glk mate & all ..
