Hey whatup, I practice mindfulness meditation at least 45 minutes a day. My advice is to start small, 10 minutes is pretty darn good when your first starting out. Any meditation is good meditation. Don't beat yourself up when you start to get distracted, this is what meditation is. You try to focus your attention on the breath but it doesn't work, that's the point. When a thought comes up, just continue to focus back on the breath.
There doesn't have to be anything spiritual about meditation, I am not a Buddhist or practice Zen, I simply do it for the benefits. The benefits are subtle but powerful. At first you might simply feel relaxed but with continued daily practice you'll find some pretty remarkable changes. Here are some that I've noticed:
I am far more calm, anxiety especially in social situations is pretty much nonexistent.
I notice when I am becoming angry, upset, depressed, I can understand how and why these emotions are occurring and what truly is the source of my them.
My memory and ability to learn has skyrocketed. My semester GPA went up ~.7 points, with a quarter less work/studying.
I am far more compassionate when I need to be. What I mean is I'm not all 'I fucking love everyone, nature is beautiful', but if I'm stuck in traffic instead of getting pissed, I hope nobody got hurt in a car accident. Just an example.
I am far more creative, the scientific term is an 'increase in divergent thinking', I never try to be but someone will say something and out of nowhere my mind will just spit out something witty.
I can easily tell when people are lying or upset.
You sleep less. I was always needed at least 8 1/2 hours of sleep to feel fully rested. I had a few weeks before this upcoming semester started of no work, or anything to do, so I decided to extend my meditation practice. I started off meditating in two 45 minute sessions then eventually 2, one hour session, then my max was for a few days was at 4 hours total spread throughout the day. The more meditation I did the less I needed to sleep. When I meditated for 4 hours a day I'd usually go to bed at 1 or 2 in the AM and be up and ready to go at 6 AM and could not fall back to sleep, and I felt ready to go for the whole day.
It definitely makes you better at skiing.
Yeah but overall there's alot of new-age bullshit associated with meditation but its essentially like the equivalent of doing bicep curls for your brain. You don't really need to change your lifestyle, 30 minutes a day over 8 weeks and you'll start to see some of the benefits I've listed above, here's the science behind it:

I'm finishing up my degree this year, have plenty of friends, and get hammered at the bar every weekend. You can totally be normal and meditate. Sorry not sorry for the longwinded reply.
