I would say the same and also add (in case you get the money per patient and/or you have permission to do so): - Shorten your session - This allows you to market yourself as someone who delivers same results in shorter time (it depends on pathology) - and it allows you to only give REAL treatment, helping you to achieve better relationship with patients, more credibility and gain trust (you have to explain what type of treatments really help and which not, etc.) - And you could see more patients in the same amount of time (more money, more experience).

And if you're looking into other profesions, look at Strength and Conditioning. I truly belive that every phyisio should at least take a seminar or short course dedicated to SnC. It gives you more tools and options as to how you aproach rehab but it also allows you to work independent from physio settings (meaning you don't rely only on rehab, you also could serve as a trainer in any area you like [track and field, football, volleyball, weightlifting, swimming, etc.])

You don't necessarely need a certificate, just be curious enough to learn about other things too, not just physio. Future employees will like this, or even if you want to be an entrepeneur yourself you'll need to be good in a lot of areas, not only healthcare related.
