Hello Everyone,

Ever since I joined Codeforces,I have seen (and still see) a lot of people being stuck at newbie(or pupil) even after 1 year of practice and they keep wondering how to improve, so to help I invited over an expert on the matter(quite literally),Kshitij Jaiswal xinyster who has talked about various things like the mistakes newbies/pupils make and the practice strategy that can be used to improve.

So I had nothing to do for the past couple of hours as my Uni Data Science Course just ended and I was taking some time off, I read Radewoosh's Blog and so many comments and people arguing.

Well guys, don't get so easily offended by small things, you don't need to start arguments online to spread hate or prove your point above someone else's.

In my country, it's a usual trend that people call problems as questions since school exams, "did you answer the last question?" "dude that question was so tough" is something I always heard after exams, if it's wrong to address "problems" as "questions" then learn it and from now on call it "problem", don't get offended over someone correcting you, you should always be able to withstand negativity and criticism, cause it's everywhere, learn from it.

You are losing focus on what's important here, learning and solving problems.

Just relax and have fun, CP is something that should make you happy and I am pretty sure Radewoosh was trying to make a joke, although well it didn't land.

On another note I hope everyone is alright, already so many people are in pain and negativity due to the Covid Scene, let's not do anything more negative.

Wishing Good Health and Peace for Everyone. And now gotta study for DES.

Thank You

Honourable Mention BlueDiamond

https://www.youtube.com/channel/UC_3tixfUu4i1AXMldrULDyg Funniest Competitive Programmer I know.

PS: I also have a youtube channel and do mediocre stuff.

Inspirational story!

Motivational Story!

Okay you did well,we get it!

Be proud and be happy but it doesn't feel good to see a "motivational story" every 5 minutes!

Hello Everyone I requested my friend BlueDiamond from Romania to talk about certain problems that many beginners(including myself) face while doing competitive programming like inability to understand tutorials and underperforming due to worry of rating etc.

Check it out here.

A big thanks to BlueDiamond for making this video which I hope will help and guide a lot of people (including myself) who are demotivated or find it difficult to improve.

All the best to everyone!

I am just curious..Does he have an alternate account or is he not into competitive programming?

Always wondered about this..
