Bet for fun and not because you need the money because that is when you make rash bets and for many a path of no return.
I just bet moderate amount on lottery every draw (take it as a lucky draw every few days). I try to win back the money with football bets which I have keen interest in and take them as gauge of my analysis. It is not that difficult to win small on football if you have the capital. Ironically, striking lottery top 3 twice last year covered my losses in football and earned some extra money.
