I'm going to take a risk here and offer some well-intentioned, but unsolicited, advice and just hope it doesn't offend anyone.
TH, like life, is an opportunity to learn and none of us is ever too old to learn.
If anyone thinks they know it all, they are putting a glass ceiling on their own ability to progress and improve.
I've been in the racing and betting game literally 48 years and I'm still learning - and often from younger (well, younger than me) punters who are always those most likely to bring new thinking to the table.
I read TH voraciously and soak up good thinking like a sponge.
Here's the delicate bit.
No offence, honestly, but I think some here don't take in a word they read.
They ask the same questions week after week, they express surprise at things they've been told countless times.
"Slim is Irish and used to work in the betting industry?"
"pawras is into stats?"
"Maurice does his own ratings and loves a spreadsheet?"
Ok, these are extreme manufactured examples, but they're not far off the truth in some instances.
Whatever your "bag" - or if your "bag" changes from week to week - there's liable to be someone doing it at a high level here already and being kind enough (because they don't have to) to share bits of what they have learned.
TH is a great resource and imo, rather than myopically using it as a blank canvas for whatever system/method you're into, have a good read of it, find out what everyone else is doing.
My Dad (who I quote far too much considering when he was alive I disagreed with him half the time

) once said: "The average person learns from their mistakes. A stupid person doesn't and repeats the same mistakes. But a smart person learns from other people's mistakes and never makes those mistakes themselves."
TH is populated with people who have tried countless things, honed their approach and are happy to report on it.
So the next time anyone is considering an angle, take a good look at what others are already saying about it and what their general approach is and if you can take value from it.
The better you "get" what a forumite is about, the better you can benefit from what they're saying - read it, remember it, build a picture and retain it,
Best of all everything here is my favourite word - FREE - so it would be simply rude not to milk it for all it's worth.
