Nobody can teach actually , watch more replays from current tournaments and see how's the players perspective.

Don't play carry for starters .

Start as a ganker or a supporter . If you fail as carry , you'll carry the blame for the cause of losing.

People will report you and etc for spoiling the game.
My best advice , slowly practice with AI for last hit then try to create a new dota2 account because the average lvl will be paired thus meaning more new players.

Try playing with friends before playing in pubs because it will affect a lot.

Not lobby games but with new friends from online or real life friends.
