I know of plenty of folks who have done this and have not regretted it. Give your full time job a few months, to make sure you can handle the side gig. Then go for it. States may cap the hours total per week/month you can acrue towards licensure, but you can still work as much as you want and get paid (in the states I have seen this happen). Most often I saw people scheduling 4-8 extra clinical hours per week.
