Like hitting the top of the water, he will begin to slow as he approaches the more dense air closer to Earth. But this will not be enough to stop him pletely. If he goes too fast or spins out of control, he has a stabilization parachute that can be deployed to slow him down.

When the sadness strikes, take a deep breath and lean into it. When we run away from sadness that’s unfolding in our lives, it gets stronger and more real. We take an emotion that’s fleeting and make it a solid event, instead of something that passes through us. 當(dāng)生活中出現(xiàn)痛苦的事情時，別再逃跑或隱藏痛苦，試著擁抱它吧；當(dāng)悲傷來襲時，試著深呼吸，然后直面它。 Have declared the end of the encounter that haven39。s time, your ideas are always special to clear.
