Read a lot of dumb stuff here about stamp collecting .
Here is a few basic rules .
Buy what other people are trying to buy ,not what someone is selling .
Buy to build something ,quit buying williy-nilly because the price is good .
Build something different ,you have common material you're going to get a low price for it .
Think different don't follow the crowd.
Collect what is hard to find .
Don't spend a lot of money on fancy albums or expensive supplies ,you get little in return .
Plan for the long game 10 or 20 years ,my game is 60 years of the same .
Don't broadcast your buying needs ,the price climbs when people heard that .
Save all your invoices and records of your purchases .
Keep up with recent prices review auction prices and on
ebay know completed sales .
Don't feel your wasting money on books and other reference material .
Have a buyer in mind who you know will have a interest in your stuff .
Organize your WHOLE collection ,biggest failure for 90% of collectors who sell is the mess their collection is in.
