To abandon something is to give it up completely. If you’re in a cabin and a forest fire approaches, you’d better get in your car and abandon your cabin, or else be prepared to abandon your life.
If you abandon something, you let it go, so when you describe someone as "acting with abandon," it means they have let go of restrictions or inhibitions. Maybe you like to dance with abandon in the privacy of your own room. But abandon could also mean people have abandoned their senses. To "drive with abandon," for example, means to drive recklessly.
1.v forsake; leave behind
2.n the trait of lacking restraint or control; reckless freedom from inhibition or worry

Su Shi also founded the haofang school, which cultivated an attitude of heroic abandon.
Acting with spontaneity might mean bursting into song on the street, or throwing down your rake and jumping in a pile of leaves — in other words, doing something without thinking it through beforehand.
The noun spontaneity is related to a more common word, the adjective spontaneous. The writer Ralph Waldo Emerson said, “Our spontaneous action is always the best. You cannot, with your best deliberation and heed, come so close to any question as your spontaneous glance shall bring you.” He meant that if we learn to trust our instincts instead of weighing the potential consequences of everything we do, we'll make better decisions.
