And to answer your question: No. I have been collecting since October, so half a year. I'm only 18 but I work as a manager at a gamestop whilst going to school full time to keep up with this hobby even though I still make basically nothing. I will be putting up a display for my stuff in about a month as well. So here is my advice for you on how to go about collecting:
Make sure to put away money. I put a third of my money towards necessities like gas and food, a third in my savings, and a third for spending on whatever (Like statues). Now that that's out of the way here is how I went about compiling what to buy.
Make a list. Make a list of every piece in existence you hope to own that you could reasonably afford one day. My list contains 21 PFs, 2 Life Size Busts, and 7 MR/EFX replicas. I am doing mainly the PFs first before moving onto the replicas. I have acquired 17 out of the 21 PFs and 1 of the Life Size Busts so far. The purpose of the list is to be a checklist as well as to keep you in check. What that means is don't splurge on something because you saw something for a great price. You'll have wasted your money because if it wasn't on your "must have" list you didn't really need it.
Then just wait. Not everything is always available for a good price at any given time. Take opportunities as you see them. "Oh hey. One of the pieces I wanted is listed for $150 less than usual going price these days. Better grab it now." Even if it isn't your most wanted. It makes the hunt fun and means your collection will cost less to amass and will grow quicker.
Oh and this is just me but I would go with the PFs. Just my personal preference. I love the mixed media and bigger size plus the mythos appear to be done for anyway.
