If you are really dedicated to improving and ranking up in this game, you need to start treating this game like any other physical sport.

1. Take the time to take care of yourself mentally and physically. Although this game doesn't require much physical ability, you need the mental capacity to keep going. This only comes from taking care of yourself. Wake up early. Eat breakfast, lunch, and dinner. Work out, take a walk, do anything that will you keep healthy. You'll improve so much faster.
2. Learn the ABCs of the game. Learn how to peek, aim at head level, move around the map, etc. Watch videos to learn. Every soccer player knows how to dribble and position himself around the field. You need to learn this too, and it will take more than a day to get there. Take 20 minutes everyday to practice on your faults.
3. DO NOT SPAM GAMES. No athlete goes out and says let me play 5 straight soccer matches in a row. That's a great idea. It won't physically hurt me at all or dehydrate me. I've honestly played one game a day this whole act and went from Iron 2 to Silver 2 with a 14 day win streak.
4. Be your own coach or learn to listen and take advice. After every game, praise yourself for successful plays and admonish the bad plays. This is how you build good habits.
5. Finally, accept that you are in your rank for a reason. Imagine going up to your coach and telling him that you think you belong on a higher division team. You're going to get lectured to hell and back. I know sometimes a smurf shows up in a game, and it sucks. But if you can't handle one smurf, you're not going to handle 4 more of him. If you want to climb, learn from that smurf. Why is he dominating your team? Look at how he's playing. Take each game to learn. That's better than ranking up honestly.

These are just my tips, and I have yet to stop climbing (image below). I see so many players going about this game the wrong way, and I want everyone to improve. This game has honestly changed my opinion on esports, and I believe Valorant is actually a sport and requires the same dedication. I hope everyone takes something from this post because these lessons I've learned can also be applied to other situations in life. Good luck everyone and keep on persevering!
