Im 1800 classical on lichess but bullet I'm like 1300, so for me bullet is real strength. It's obvious I'm not great at chess
I played in anonymous mode for a long time experimenting and I realized that I was losing most of my games in bullet to time not to tactics.
For bullet: Just play average move each turn based on long term goals (I want to castle king side and pawn storm queen side etc), dont bother about tactics or traps or any other short term strategies.
