Well, I'm not selling any off my stuff. Worked hard to build my collection of Yammies. I don't consider myself a valkaholic. I display my stuff, bought one of each (not the case of my extra 1/60 VF-1A Hikaru which became a TV VF-1 Max and my 3 GBP sets).
I pay my bills, work hard, enjoy life with my girlfriend (soon to become my wife next year ).
Plan your spending, pay your bills, think of your retirement and enjoy life. You won't need to sell your collection
