Feeling like losing and a failure!

Am 19M here doing my college.From a middle class family.I want to taste success in my life.I know that I need to work consistently inorder to achieve my goals..

But am not able to maintain that consistency it's like I do for a week and then give up for 5-6 days and then start again and repeat the cycle.

I wish to improve myself in physical domain as well and want to join gym but knowingly procrastinating it.....

I genuinely want to improve living conditions of my family....

When I see my friends in college all are busy with their gf's...some are son of rich dad's....

I really felt left out in life and think that maybe I will too endup struggling life like a mediocre.....

But when I consistently work towards my goals take it study,getting up early etc... I feel that I am gonna conquer the world....

Really am confused and wany your advice...like am good in studies and coding stuff etc....But....

My distraction:My fucking phone with youtube installed in it.....
