It all depends on your capabilities. If you have the opportunity to hire staff, such as a masseuse, tennis coach, driver, cook and maid, then of course you can do it. This will save your time. If you think that your time is expensive, then of course you should use the services of a specialist and thus save money. How do you think. How much is your time worth? Is your time worth more than the time of the trainer you are willing to pay?Do you think it is worth hiring a poker coach to play better, or is it better to learn on your own with WODs, books, videos?...
Because I want to spend time with pleasure, but so that there is a profit from it...
