"play the London with white. With black, I play the Scandi/Caro against e4, and the Dutch against others." ++ OK
"I play mostly 15|10" ++ Excellent. But do you use all that time? Most chess games are essentially decided before move 30. So spend all your time before move 30 and finish the game on increment alone. That gives you average of 40 seconds per move.
"I tried hard not to blunder" ++ Blunder check before you move.
"my opponents just surprise me with some crazy moves" ++ Consider all opponent's moves.
"I will lose all of my games when I find myself in a defensive position."
++ Defense is difficult. Study some defensive grandmaster games. Example:

"really want to get to 1000." ++ It is mainly a matter of blunder checking to reach 1500.
After rising from 300 elo to 700 elo in 3 months, my rapid rating starts to plateau.
I mainly play the London with white. With black, I play the Scandi/Caro against e4, and the Dutch against others. I play mostly 15|10 now when I have the time.
I tried hard not to blunder pieces to simple tactics, and find simple and forcing moves to attack, but my opponents just surprise me with some crazy moves and I have to defend. Basically, I will lose all of my games when I find myself in a defensive position.
Any recommendations (e.g. tips, learning resources) for me as a newbie? I feel frustrated with how dumb I am at chess and really want to get to 1000.
