Beware of False Idols
No one way is best. Nobody has it all, no one has all the answers. You are smart enough to do your own research and work out what is the best course of action for you to achieve your goals. Seek quality advice from sources who will put you before themselves and their wallets. Just because something is worldwide and or originates in a foreign country it doesn't necessarily make it better.......
The world is full of amazing and interesting people with stories to share and things to teach. However, never overlook the local guy or the guy a few towns up from you who I'm sure can teach you so much without the need to travel to the ends of the earth.
I think in the UK and Europe, we are very prone to look to the USA as if that country holds all of the expertise. We see their athletes and assume that they have all of the best techniques and approaches. They quickly assume guru status. We need to be more confident in ourselves and our expertise, not only as individuals, but as a nation.
