Great starting points for developing a meditation practice. It takes some initial effort to "do nothing" when everything around us is geared up for doing more and more.

There is one point I'd like to add if I may. Images of meditators outside are very common and it seems like it would be wonderful to practice in the open. If you wish to meditate outside, I would highly recommend not to do it in direct sunlight or in breezy conditions. In meditation we open up our energetic body, we let go and release, we widen up the space we inhabit. Even after spending a day out under summer sun we often feel tired. If we meditate in direct sun, instead of creating more energy (pranayama, qi, life force) we deplete our "battery" at accelerated rate. Same goes for the wind. Even mind breeze can pick up and blow away our energy quite easily as we are more open, more receptive and more vulnerable when we meditate. Also bugs are very distractive during meditation.

Nevertheless by all means meditate! Usual physical and psychological benefits attributed to meditation are wonderful, but there are truly only byproducts of much greater process taking place. Big things can only be appreciated from a distance and most effects of meditative practice are not seen right a way.
