Pizza dough won't stretch and will tear… what to do plz…? Newbie

Hi. I am new to this forum. I like cooking and trying new things…. I have been struggling at making a decent pizza dough, even more  struggling at ” forming” a decent looking pizza , mostly because I just can’t stretch the dough without tearing it. I always end up with  a product that  is nowhere near round, full of uneven thickness, not homogeneous mixture….my dough wants to spring back so bad….

I use bread flour 00. 

my recipe is :

7 gr dry yeast (the fast one)35 gr olive oil245 gr warm water500 gr bread flour10 gr salt. I mix all the ingredients  by hand and leave it to rise for half a day in a warm place. knead one more time and leave for a couple of  hours to rise. divide , make balls,  start attempting making a decent pizza dough…I don’t knead much because I do it by hand and it’s quite a workout…. would that be one of my problems ? I don’t ask to be as good as this guy on youtube…. Look at the way the dough is reacting…. it is solid and stretchy….why can’t I make a dough like his  Please… ? Please help 🙂 https://www.youtube.com/watch?v=kyPTK0nOwqg thanksStef, Montreal.
