Just a small note, you don't have to do nothing to practice mindfulness, I do it all the time while driving, walking, or doing anything that I have on "autopilot". All you need to do is be non-reactive; when you experience something (including a spontaneous thought), stop your mind from automatically pulling up associated thoughts and memories.

I find it helpful to remember that the sentient fraction of matter in the universe is vanishingly small, so your ability to experience is truly a blessing. Mindfulness occurs almost by accident if you just focus on savouring your experiences.
