Do I need a personal trainer?

Do I really need a personal trainer? Or do I need an education?

Personal trainers should be like a teacher not like a drug that sticks with you for 2-3 years.
Anyway, there is a difference between personal trainers for normal people and personal trainers for athletes.

Exercising and eating healthy became like rocket science. Only personal trainers have the secret information on how to become healthier, stronger and fit and this is a marketing tactic to keep this industry alive because otherwise, this whole industry of PT will disappear in about 5 years if PTs will become teachers.

Think about all the schools and all the supplement companies that certify PT and help them make money by selling supplements.
To go and run, doing squats, push-ups, pull-ups, skipping rope, etc. You don't need a personal trainer. To understand that you must eat more veggies, fruits, regular meals, etc. You don't need a personal trainer.

For all of these, you need education. Education about basics.
You need directions.
