What works for me?
Well, I think sila (= Pali for virtue, i.e. virtue in regard to what you do the whole day) is very important.
It is very good to do good deeds. It gives you contentment which removes restlessness, during your meditation you will tend to feel "there is nothing else to do than to meditate now."
What are good deeds?
There are infinite ways to work on your sila. Here are some examples:
-Be kind to other people
-Work well in your day job
-Help other people
-Move your body much during the day, a hobby in which you move the body a lot helps
