I'm one of those outlier people who gets interested in the fields where the majority is usually wrong. Strength training and personal investment are two such fields. It's great to find that minority community (and yes Bogleheads are still a minority) where information is correct.
Personal training and personal investing have lot in common! Firstly, both are a minefield because
- Most internet information out there is unhelpful or often wrong
- Professionals make it out like it is complicated and needs you to pay to get the right custom plan
- Professionals will make overly complicated plans for you
- Professionals will charge you huge sums for their services just because you don't know better
- Over the long term, you don't get the gains you could be getting due to the cost and complexity
- What people think is important often is not what is actually important
- Investment and strength training are both very simple
- 2-3 funds, or 4-5 compound lifts are all you need to get going
- Set a plan and stay the course!
- It is psychological - it is hard to believe that simple can be best
- If all you do is the basics, you will be ahead of at least 80% if not 95% of the population
- The time and effort in self learning the basics are well worth it compared to paying pros
- All the advanced stuff doesn't make as much of a difference as one may think, even though it is fun to talk about
For those not familiar with strength training, I'm happy to take Q&A on this. For those who want to know where I'm coming from, the canonical source is the book Starting Strength by Mark Rippetoe (https://startingstrength.com/).
