please HELP, I'm new to mysql so I have a question  about the best practice, I'd like to have users to choose intrests or hobies so I got 2 tables:  "users" and "intrests" and I'd like to let users to choose multiple intrests, how should I do so? 
should I create a new table : "chosen intrests" and associate user_id and intrest_id together? how is it usually done? 

I'd really appreciate Your help, thanks

just a small advice for future videos: try to smack a little less and talk a bit more fluid. its hard at times to follow the speech if both is not given.
