Learn exactly how to think in the opening, middlegame and endgame — this is what I teach.
Always blunder-check your moves.
Solve tactics in the right way.
Analyze your games.
Study games of strong players.

Work on your time management skills.
Get a coach if you can.

Start your training plan by playing as many bullet games as you can. Lets's say 8-10 hours a day for one week. That's what I do when I feel my brain getting lazy at chess. Then after that start studying and solving for another seven days. No playing. For five hours a day. And repeat if you want. Mix it out. Have fun.

"Obeying chess coaches is a good way to improve" ++ Not really, no single formula for chess improvement. You got to find your own rhythm that keeps your chess brain working.
