Maybe you'll miss 2-3 days in a row — now you've lost motivation, and you're discouraged. It's better to do it in small doses, because it's easier to get started when you know you're just doing 10-15 minutes, and it's easier to find the time and motivation for small sessions.
Bring the magic of small, regular practice to your life!
