I'd really focus on avoiding blunders and then learning strategic ideas step by step. Try to play some tactics, they'll help you train to think some moves ahead and you'll probably avoid some blunders because of that.
Take a look at this game you played: de.lichess.org/wZd9w1eT#62
It is very unfortunate to lose such a winning position to an avoidable mate in one. There were a lot of strategic ideas, from the second move on. If your opponent opens up the king's diagonal (2. (...) f6) so early in the opening, that can't be good for him and I really could not resist to play Qh5+ in certain lines. I guess those ideas will increase with the amount of played games and trained positions, so keep playing.
Btw.
@jonesmh #5 7. Qd4 should be winning for white.
