Im getting my license and i have a question?

so at first i could not wait to get my license finally, im 17, and i was all stoked and what not but now that i get it in a few more days im getting quite anxious. i cant imagine me driving alone...and i see people like my friends and parents and people drive so fluidly and relaxed and effortless and i want to know how they do it. ive also been in a lot of close calls when it comes to accidents and i always say holy **** if that was me i definitally would have crashed and died. any tips from experienced drivers???????
