In English "Productivity Club" initials are "PC" but in Estonian it does not work (because it is "Produktiivsusklubi"). Since in the beginning we will mainly use the logo in Estonian the logo should not have initials "PC". It can have just "P", because that works in Estonian well.
Our main focus in Productivity Club is to help people put things in practice not just learn theory. To actually apply ideas into their life. So if you are somehow able to put this meaning in the logo, we will be excited.

"Produktiivsusklubi" is "Productivity Club" in Estonian. We are starting our brand here in Estonia, but in the future we hope to expand to other countries. That means, we would need two versions of the logo. One in Estonian ("Produktiivsusklubi") and the other in English ("Productivity Club"). The icon should remain the same, just the text in two languages.
For design ideas, a mountaintop is something that could fit, however this is used quite often, so it might not stand out so well. We want the logo to be simple with an icon that can be used separately as well.
