As for my self i started from super skinny guy. I've been lifting for about 1 year already .
There's a lot of gain already but still i feel i'm not making much progress..
Started from 60kg bulk up ---> 80kg . Now im on cutting phase weight@75kg .
I eat well , rest well , lift everyday ( including deadlift , squat ) , cardio every 2 or 3 days..
but my chest still pretty flat , back not wide , arms still small not a single vein can be seen etc.

I know a guy a friend of mine who used to be really fat ( Obese ) just started to working out not even half of years , now his body is more well defined and more muscle better than some guys who have been lifting for years..back are wide , traps are huge , arms well define and massive vein on it..legs are huge etc.
but if he is shirtless , u can see that he have excess skin ( i don't know what to call it ) around his chest and stomach..
but he makes really fast progress while i'm really slow i guess..

So my question is , am i progressing really slow ?
Is there any difference comparing a guy who started skinny with a guy who started fat ?
Any tips for me ? Thanks

Thanks for ur feedback bro..really make me feels motivated again .
I admit it that sometimes i feel like giving up after seeing people around me making really fast progress.
Sometimes i feel disappoint with myself seeing them working out once in awhile ( on and off ) but they do have well defined body or at least better than me .

My routine as for now -
Monday - Back / Bicep
Tuesday - Chest
Wednesday - Shoulder / Tricep
Thursday - Off ( Rest ) / Jogging
Friday - Legs
Saturday - Chest
Sunday - Off / Jogging

* I workout my chest twice a week because my chest really weak and it's the part that i really don't see progress.

My diet as for now :-
Breakfast - 2-3 Eggs or Oat with cup of milk
Lunch - Rice with egg + chicken breast + vegie
Pre workout - Usually i just eat bread with peanut butter
Post workout aka dinner- 1/4 steamed chicken ( Sometimes with rice )
Late night - 2-3 boiled eggs / breads with peanut butter.
