I think the more you play the better you will get
Seems fair enough, mostly. I do find at points in my life I have not been enjoying chess and I think playing then has not helped my game. Also, although I have argued previously that all play including blitz hammers in patterns and allows experimentation, there is an extent to which bad habits will be learnt also and that cycles of mistakes can demoralise and lead to disimprovement. Attitude and approach are a big factor in progression, disregarding innate talent for now. I am not sure that playing 30,000 French defences would improve your general play as much as trying every opening system a few times each. On an aside, your other comment about not being a grandmaster....I am certainly not either but your opinion is as welcome as the next person's, just sounded a little bitter?
I think the more you play the better you will get, this is not coming from a grandmaster with 25 years of coaching experience so if it doesn't work for you then I'm sorry. I play play play on chesscube and have gotten about 200 to 300 rating points better at standard games (now up to 1700) from playing bullet chess on chesscube.
