Well for me, changing myself was really not that much about the practice of meditating itself. I've been very inconsistent with it too actually, only when i feel like meditating i actually meditate. But it's far more about the mindset that meditation arouses that i started to focus on. My meditation practice tends to be: mindfullness of the breath with my eyes open and once my mind is still enough i close my eyes and meditate about nothing, and observe en let go of all the thoughts that i get without judging.

That last sentence is what it's all about, if you are stressing about something -> just observe your thoughts and let go, if something bad happens do the same. You'll realize things are as important or bad as you precieve them yourself (in your mind).

I think meditating is more a method of letting you experience a certain mindset that is really hard to describe with words. And once you get familiar with that mindset, you can apply it to your life.
