There’s nothing that beats habit and practice. You can’t say you want to be a strong weightlifting champion like Schwarzenegger and you spend your days on end doing anything but exercising, it won’t happen. Best thing to do is to get up and start doing instead of just talking, do it. Just go for it! If you’re willing to change, saying you will change won’t actually make you change, doing the things that will change you will bring about that change.
I remember one time in high school I was always an average chess player because I used to play it sometimes, I decided I wanted to improve and from that time I started spending a minimum of 3 hours
So what are you waiting for? Get up, less saying and more doing.
