They reckon that there's only two certainties in life: death and taxes.
But I'd argue there's one more certainty. Tom Waterhouse blowing his own trumpet.
When the young multi millionaire isn't telling punters about his fine racing pedigree and the knowledge it's blessed him with, he's going on about how he built his gambling empire from the ground up, and coming back to the good side.
He's one of us now. Apparently.
Whether you like him, loathe him, or couldn't care less, it doesn't really matter.
That's because the man whose love of the "good life" is only surpassed by his love of tailored suits, really does know a thing or two about horses.
Don't take my word for it. Look at the stats.
Tom Waterhouse's tips - the stats
Since theGreatTipOff.com started recording Tom Waterhouse's tips in May 2018, he has provided over 400 selections for his customers as part of his Daily Best Bets package.
His tips from this package have landed 173 winners, at a phenomenal strike rate of 42%.
To put that number into perspective, it would be like tipping 4 winners from a 9 race card every Saturday of the year.
Considering most of us struggle to find two or three winners in a good week, Waterhouse's strike rate is very impressive.
But do these winners translate to a decent profit?
You bet they do.
How Tom's Tips stack up
Using best tote starting price rather than the best Fixed Odds price which Tom uses to display his results, Waterhouse's tips have yielded an impressive 12% Profit on Turnover (POT) for his followers.
If you wagered an even $100 stake on all 400+ tips from Tom Waterhouse, you would currently be sitting on a cash profit of $5,075.
On our all time leaderboard for media tipsters in Australia, this total puts Waterhouse right up near the summit, in 7th place.
For those who are interested, that top rung is currently held by Racing.com analyst Grace Ramage, after her solid 2019 effort.
But knowing Waterhouse and his undeniable drive, he'll be eyeing off that top spot.
And with the form he's in this month having racked up 57% POT from his 14 selections, he may be up there sooner rather than later.
Interestingly however, punters who have followed Tom's suggested stake for each of his tips, only find themselves up $179 since May 2018 from $100 win bets.
This suggests that you're better off backing his selections with an even stake.

Where Tom performs best
But now, let's delve a little deeper into Tom Waterhouse's tips.
What's interesting is that he doesn't just focus his efforts on his Sydney Eastern Suburbs stomping ground of Randwick Racecourse.
The statistics indicate that he performs best at Victorian metropolitan tracks, where he's reeled in 48% POT over the past 365 days. This ranks him second amongst the best performing media tipsters at Melbourne tracks.
That will be music to the ears of Spring Carnival punters, who will take comfort in the fact that Waterhouse knows how to perform on the big stage.

Even better however is that Waterhouse doesn't limit his tips to the major metropolitan tracks, finding winners everywhere from Murray Bridge to Goulburn and Gunnedah. Dispelling the myth that Tom can only do form at the big metropolitan tracks.
If Waterhouse has anything on his side, it's resources.
Apart from having access to one of the best racing minds in the country, his Dad Robbie Warterhouse, he also has comprehensive statistical information and analysis at his disposal.
Our sources tell us that the Waterhouses have collected racing data for many years including real data for multiple factors that can influence the outcome of a race. These statistics are analysed using computer models to look for patterns across these factors.
Like all good professional punters the Waterhouse's price each race market and look for differences between available odds and the Waterhouse's assessment of true odds. If they get it right, which they do, it's like getting $5 odds backing heads in two-up.
Their statistical analysis is overlayed by Robbie and Tom's own analysis to select their bets.
With this approach in mind, it's easy to see that they're most likely doing better than Best Tote prices. Much better.
Do they get the top fixed odds price every time, as used on his results page? I doubt it.
There is no doubting however that Tom's doing well on the punt. Very well.
