Ive been working with a personal coach recently and at the start of each session we start with a guided 2-3 minutes of mediation practice.
One way to do on your own is with mp3's and doing on your own. Really from my personal experience thats not expert driven at all, even doing 5 minutes a day before you day starts is a great way to start for weeks or months on end.
Just those 5 minutes of calm and awareness can do a lot, it has for me.
