Less glib edit :) I should probably give you a tip. Say to yourself, “I am a meditator.” Now, imagine someone asking you “oh, when did you last meditate?” What kind of meditator are you? Are you one that can answer “I meditated today” or “I meditated yesterday and I’ll do it again today”? Or, will you answer, “I meditated last week” or “it’s been a slow month for meditation”?
If you can’t say “I’m a meditator” and mean it, then you should just stop thinking of yourself as one who meditates. You don’t practice meditation in any real sense. That’s the rules of discipline. You are what you do and you aren’t what you don’t
The 30 days, 100 days, 1000 days mastery I got from my yogi who taught me kundalini yoga. She said it's basically a habit after 1000 days in a row. Good luck!
