If you are "trying" to reach a happy state, you are meditation with the incorrect intention, and incorrect view, or objective.
Meditation is not about reaching a state of happiness.
Meditation is about abiding in the moment, and letting things arise, drift and pass without attaching any importance or significance to them.
You observe the thoughts that come to your mind, but you do not hold on to them, or focus on them.
Let things be, do not participate in anything that arises, but notice them... and let them go.
Observe your body as you breathe, in and then out.
Rest in calm abiding and simply sit.
serenity, happiness, inner peace, joy.... these develop within meditation and outside of it.
But they are not the objective.
I hope you understand my English, and that I have put forward my own opinion, clearly enough for you.
