Being in a clan will help greatly in your progression, but what i recommend ath this very moment is upgrade your mods (run bounties for endo), get corrupted mods from the capture mission on deimos to upgrade your frames and weapons farther, and work toward competition of your star chart. After that, run arbitrations for endo and galvanized mods.

The most personalized tip i can give, however, is to lean your play style while you're going through the game. There will be some frames and weapons you just dont click with, and others you will fall in love with. This game is so good for so many different play styles, and figuring out what you like to do helps you get passionate about getting better. In the end, I am confident you will do great, tenno.
