There are plenty different types of meditation that you can look into.

To start, try to sit for just a minute or two, lightly close your eyes, and slowly count your breaths in and out without trying to control your breathing. Each time your mind wanders, bring it back to your breath.

I don't remember. I started mainly to help with anxiety, and looking back I'm able to see all of the other positive effects it had.

My recommendation on conquering procrastination is to take small steps. Try to get a small win each day by not procrastinating on ONE small thing. Then celebrate that win and build on it instead of focusing on the negatives and other things you blew off.

One of the side effects of practicing meditation is procrastination pretty much went away completely.
