I, personally, feel that I learn well from watching many instructive videos on youtube made by professional chess players and streamers.

I have been stuck to 1000 rating for a while and i want to improve and reach 1500 rating (current goal) but I just can't go up from 1000, any tips to improve ?
Extra note: i only know and play the king's pawn opening.
