What do you mean "most people can't do what it takes?"
Are you referring to capabilities or persistence?
What does it take?
Often, people have the misconception that to effectively meditate one's mind must be clear of any thoughts. Well, good luck! The mind thinks, that's what the mind does. We can't hardly tell ourselves to stop thinking. But, with practice we can become more effective at neither fighting nor following the thoughts. Being anchored in the body and following the breath is the vehicle. There are myriad ways we can practice throughout the day.
Jon Kabat-Zinn, who largely developed Mindfulness-Based Stress Reduction, asked the audience at a lecture I attended: "When was the last time you took a shower, that you were actually in the shower?" What he was referring to, is that so often we are disengaged from our activity. So, instead of already being at work or having an argument with someone who's not even there, we actually are present with the experience - feeling our feet on the shower floor, sensorially experiencing the water cascading off your skin and counting your breath.
So, give it a go - it will definitely help your game.
