I'm a bummer and it's time to get it over with

I start trading normally since Monday. I usually make a couple of trades and close with a plus., it severely limits my profit. And then I do other things instead of increasing profits. I don't give it all 100% , I trade on 5-10% from their capabilities. People trade all day, чтоб добиваться таких результатов, and I put in a minimum of effort and take my crumbs in comparison with what I could already achieve.
It is necessary to increase the size of positions in 2-3 times and earn in 5-10 times more. My trading is based on statistical advantage over the market, the more deals, the more I earn by following my strategy. It's time to stop being lazy and slovenly, apparently I forgot how many years I had to go to my knowledge and decided to bury it, so much time and effort was spent, to take now and stop when everything goes well, well, I do not. I have to become a better trader ...
