Well thought out and written responses. This comes up from time to time here, and I always like reading these threads.
Another perspective...
Sports gambling is difficult, but everyone wants it to be easy. That might be the simplest way to describe why so many lose and so few win. For me - about 25 years ago I made a decision that if I wanted to keep sports gambling, I didnt want to lose anymore. So I put in a ton of work. I figured some stuff out. I studied (literally took college courses on stats, game theory, and probability). I put in the hours, hundreds and thousands of them.
I took the emotion out also. This is a key. It is really hard to be successful long term with emotions.
I have been able to make a career out of this and do very well. But only because of the discipline. And a few other ingredients in the soup....
1. I have made handicapping far less important than what it is to the average sports bettor. I do this by increasing consistency, and decreasing standard deviations. Someone recently posted in one of my threads (as an insult) that I am "good, but not great". That is a huge compliment for me. I want to be reliably and consistently good for a long period of time. That is enough.
2. Multiple streams of gambling income. Covers format really only allows picks. But for me - I buy and sell lines all week - very often resulting in games where I have zero risk and lots of upside. But either way, this is a huge income stream. It takes a lot of work. I stare at screens all day. I work to have dozens of outs at every sports book.
3. Reliable OBJECTIVE models. Forget how you feel. You need some kind of stats model that works predicting some kind of results.
4. Zero emotions making decisions. Treat it like a business. Treat everything like a process. Consistency.
5. For me - I only do this for about 8 months a year. That has proven to be great for me. I get time to recharge, learn new things, improve my process.
This has resulted in a life where I havent had a real job, and a life that has long periods of vacations. It also has downsides. Many. But overall - it has been great for me and my family. I would have never been this successful in a real job in the real world, so I am thankful. It also has resulted in an infinite bankroll. I realize how that sounds - but I literally do not have a bankroll anymore. The amount I need to bet to reach my goals is way lower than what my bankroll would be - so I dont even worry about it anymore.
Put the work in. Find your own slice of the pie that can be replicated. It aint about picks. Picks dont mean much. You need process. Replicable process.
So instead of looking at it as "winners" and "losers", I look at it as people who want to win and people who want to have a hobby or have fun. If you want to win - you have to wash your brain of all of these bad habits like actually caring about what the OP wrote about bet percentages (they mean absolutely ZERO). Wash yourself of the noise. You have to commit to learning, and finding a process.
Everyone will read this and think this is them. It is not. It is not for you. You dont do this currently - no matter how much you think you do. You have no idea what this takes. But it is possible.
Continued GL to all.
