You can never allow yourself to bet scared!
No game you want to invest in should ever be missed because you don't have the finances to back it up. Determine an amount of money you can afford to lose, not for one weekend, not for one month, but for the season. Set that money aside for one purpose and one purpose only...as a bankroll for football season. Don't touch it or use it for anything else. If you're reading this prior to the start of the football season, start setting aside funds for your bankroll right now! Do not wait for the season to begin.
Once you've established that bankroll, invest 3 to 5% of that bankroll per game no matter what happens.
For example, if you've determined that you can afford to lose $3,000 for a season, you should invest $90 to $150 per major play. If you choose $90 per major play (or 3% of your bankroll) then stick to that figure throughout the year.
It takes an unbelievable amount of discipline but it is a key to success.
Examples:
$1,000 (Bankroll) x .03 = $30 per game
$2,000 x .03 = $60 per game
$3,000 x .03 = $90 per game
$4,000 x .03 = $120 per game
$5,000 x .03 = $150 per game
$10,000 x .03 = $300 per game
