Usually a only once a day before I go to sleep. I would rather get going in the morning, and meditation doesn’t help me do that. Because I want to keep the momentum for the rest of the day, I wait until I go to sleep to meditate because it makes me feel ready to sleep and calm.
Tbh, 10 minutes a day is sufficient. This kind of re-energise you up and you start feeling better. Even better if that's the first thing you did after you woke up.
