With the micros it is all about value. Do not expect fish to put in money for you when you have a good hand. Bet your set of Kings on the flop incredibly high, maybe go all-in while you still have the best hand - the fish don't look at the bet sizing and will still call if they have any type of draw with terrible odds
As for the bad beats, it's just part of the game. You might lose this time then win the next 2, or lose 3 and then win the next 6 - but just bet for more value while you are still ahead and fold if you ever feel you are eventually behind... do not make hero calls on the river or try to bluff against a fish.
It can take hundreds of thousands of hands to level out but it probably does eventually. I have been down more than 10 buy-ins at 0.01/0.02 and came back to be up more than 100... you need a lot of patience. It is not for everyone. Most of the time you beat yourself by getting frustrated. You need to be in there to make good hands like sets and flushes and hope your opponent catches something slightly worse and bet into them for value.
If you think you are unlucky or that the game is rigged against you or that you have worse variance than others then take a break and play with play money and go up the stakes there - just for a challenge. You will still see the same sick things happen, even more-so because there are even more donks. Once you get up to hundreds of thousands of play chips then people take the play game more seriously and it can be just like playing with real money
at micro stakes.
You will see the game is just the game, the money is just the money, and your emotions are just your emotions. They can all exist separately. They are not that relevant to the game. Furthermore, equity is just equity. Having 51-99% does not mean you should win any hand. You will just win more hands than your opponent long term as long as you do not make the same mistakes as them.
