Hello !
First step : You should rezolve 10-15 problems per day.
Second step : You should know +5 openings , you can ask someone what openings ( + you need know how you play (( you like solid position or you play open position <= you can choose many openings )
Exemple :
White : The English Opening
Black : Paulsen ( Sicillian ) , Nimzo , Bogo, Aleckine
( I love Solid Position )
3rd Step : Don't play bullet ( 1+0 or lower or 1+1 etc ) play at +5mins because it ruins your game , when you will play at tournaments +1h in real word , you think you played that , at bullet you dont see the combinations or you can stay very bad
4th Step : You can look in Chess Books , GM Games , to play on chess.com ( online chess ), and don't use engines ( ip ban 3 months )
