It is not "growing". It is changing the work which can be good or bad. I "grew" to a manager (CTO in this particular case) in 100 person company some 20+ years

It is not "growing". It is changing the work which can be good or bad. I "grew" to a manager (CTO in this particular case) in 100 person company some 20+ years ago and this got me to the point that I said fuck it, went on my own and am still happily doing creative work designing and implementing (including programming) products for clients and for my own company.
