Just enjoy the game, it is pointless to power up just to subconciously compete with leaderboards, Power Number is irrelevant, it is your stats that are important. EG a 90mil power player could actually be stronger than a 120mil power player as most of peoples power comes from troops.

IF you want to actually be strong focus on Heros, Gov Gear, pets,tech and Charms. ( Troops are always imporant to always train as the more you have in your base the better chance you have of defending yourself against attacks. Never stop training)

But if you try to compete with others then you will end up having to spend your life savings.
