Act Coo'.

Being Spontaneous does not just mean that you're able to make up your own plans on the spot, it means being able to be comfortable with uncomfortable situations. For example, you're out with your family or friends, You've made your own plan to go somewhere but, unfortunately, your friends had a different place in mind, some people don't care, some people do but, you gotta' learn to flow, just be comfy, I mean your with your friends right & if you really wanna' go to that place, talk it out, maybe get a rotation running for your hangouts or something. another example, you're at a relatives house & you kno', you bored as hell, it's Sunday, you just wanted to get your own stuff done but, you're stuck there, your parents told you that you gotta' stay for a couple more hours, you ain't even doing anything there, your Moms over there talking with a relative you barely know, your dads doing the same & you just wanna' head home, you wanna' whine but remember that shit ain't worth it, ahahah. so just talk with the people around you, better than whining, think about your parents too, maybe they haven't seen these relatives in a long time.. just act coo'. 

Being Spontaneous extends further than making plans or being out, it also applies to your whole life, the time you got, either we got put in a uncomfortable place or we gotta' force ourselves into one to progress, we gotta' learn how to sit down with it, be comfortable.
