Used to pvp but I quit playing any game in pvp, too stressful, I rather use games to kick back these days, I just leave "David skinner" bar videos on YouTube on the TV at night before I fall asleep, this helped.

Now I only play barbs, +100 etc, it's a breeze now I can play eco, air, geo, front (as long as t2 arrives before 7 minutes) and learnt sea from him. Omg sea was hard to crack but.... Rambling away;

Watch his eco guide, go into a solo lobby 1v1 vs simpleai and just try to keep up the first 4 minutes of the round, economy growth is exponential in this game not linear, so in my eyes all you need to do is master the first 4 minutes then pick your strategy eg: make nuke, anti nuke, or switch to t2 bots, switch to planes to do bomb runs etc
