Most people misunderstand what meditation actually is! 
It's a must to get rid of the mind completely. This misunderstanding ruins meditation for many people. People sit down, close their eyes and realize they are thinking about food. Then, they say to themselves: "I'm not good at this." Then they quit. A wandering mind is not a meditation failure. It's the whole idea. It is not a practice of reaching some kind of blissful empty state of mind. The practice is noticing your attention drift and gently returning focus. Awareness itself is the training, not achieving silence. I once heard a meditation teacher say: "A thousand times you think, a thousand times you forget. Bring it back 10,000 times." That is meditation. Simple, but difficult. There's a myth that meditation requires long sessions every day. But who actually made that rule? But it is what it is, it turns off almost everyone who has a job and responsibilities to do. Five minutes is enough. Even three minutes can help. Even short, regular sessions, there is good research that can show over time, the brain rewires the stress responses. Regular practice beats occasional marathon sessions. Someone meditating 5 minutes daily will usually outperform someone doing one long session occasionally. Start wikipedia reference with something almost too easy. Try just two minutes a day. Meditation is a religious practice. Meditation is a religious activity. Meditation does have roots in Buddhist, Hindu, and other traditions. So does yoga. Similarly, the calendar you use for meeting scheduling. Meditation can be completely secular if you choose. Mindfulness is practiced in medicine, sports, and high-performance training. As a card-carrying skeptic, you can still garner a lot of benefits from the program. Use spirituality if it helps you, or ignore it if it doesn't. There is no single correct way to approach meditation. Many people expect instant calm from meditation. That expectation causes a lot of disappointment. Other sessions are like watching paint dry, with your brain shuffling through multiple versions of all your anxious thoughts. That experience is part of the process. In some sessions, you'll bump into something muffled and soft and it's just a really difficult thing to describe. Also normal. Like fitness training, meditation rarely produces instant transformation. Inner calm develops slowly through consistent practice. Think of meditation like compound interest instead of instant rewards. You Don't Need To Sit Cross-Legged: The stereotype of perfect lotus-position meditation confuses many beginners. That image mostly comes from traditional art. Unfortunately, it creates unrealistic expectations. Sit in a chair. You can even lie down if needed. Stand. Walk. Meditation isn't limited to sitting still. The important thing is that you are alert, and are not battling the posture. Mental clarity matters more than uncomfortable poses. Meditators are not perfectly calm all the time. Meet some long-term meditators and you will see that they become irritated in traffic, as do all of us. They have bad days. They still make mistakes in relationships. Meditation doesn't make you superhuman.
