Luckily enough you are so much younger than the majority of people who start these escapades, so you have time to do both!! Personally, I'd sort your life purpose first, then at least, that will be in place and less monkey mind to battle with when beginning intense meditation retreats and you won't have to worry about finances. You are only 21, enjoy and experiment in the game of life.. :-) I am 28 and feel like an old fart... But understand I am still on the younger side to be on board both these adventures, so I am happy with that. X
