I'll speak my piece, although I will draw criticism because all minds think differently. I do win long term, especially in baseball. It took me MANY years of losing before I learned how to win. I'm sure you've heard of the school of hard knocks. I'm gonna break down what you said to the simplest form.
1. Your winning games but losing money. Signifies your on too many favs. Don't be afraid to play an underdog. Thats where the value is. Once you become accustomed to doing so you'll become addicted to it. You'll learn that getting juice instead of getting it is a nice feeling. Logic says dogs in bases are the way to go seeing as though so many teams hover around the .500 mark, even some of the bad teams. Your best value is with your worst teams. Not now, but midseason go look at the good teams and you'll see you would have performed worse betting them monetarily than the bad teams. Another idea for you is to strictly play totals only so you don't get caught up in juice.
2. Pick out your strongest play of the day and only play that play. Regardless of whether you win or lose. If it loses, you play tomorrow. If it wins, you play tomorrow. Don't play off wins and don't play off losses, both play an emotional roll that gets the best of us every time.
3. Parlays are a horrible proposition. You stated you play one par at 10 bucks a day. 10 bones a day is nothin'....But X 30 days in a month your looking at 300 bucks and thats most guys bankrolls/amt they deposit into books from their paychecks monthly. Their ok for recreation if say you make over 200k a year, but for a small player, shit no.
4.Money management. Play 100 dollars a day on one game. Just do it. Build self discipline or you will go along the wayside just like the other 75% of the posters that come and go after a year. Bases is very beatable, you just gotta learn how to do it. Most guys say they have self discipline but they dont.
5 TV games, are you betting all of them? If so, play this system. Bet the underdog or under the total on every tv game. It will most likely make you money and at worst keep you close to breaking even if your losing.
6. Why do I care? Cause I don't like bookies. Also, I'm too damn old to play ball anymore and this is another form of being a member of a team. I like to help and have some extra time on my hands. Follow these steps and your betting life will become much more simple.
It wouldn't hurt to follow meatman until he cools off either. Guy is unconscious! Good luck bro, I hope you figure stuff out!
