- Know your Budget
Prepare your money, cause money is the most important thing in this business. No money, No Gunpla. so when you decide to buy a gunpla, choose gunpla which is fit in your wallet.
one thing , never buy a gunpla if you dont like it. it's okay if you don't wanna build it, but it's really useless if you buy a gunpla only because your budget but you don't love it. - Know your Ability
If you buy a gunpla, at least you know how to build it. many collector bought a gunpla and didn't build it cause of limited item, expo. that's okay and sometimes i did that too (if i ever have a limited gunpla). but if you don't know how to build and you didn't even try one gunpla to build? my advice, don't waste your money bro. - Know your Seller
try to bought a gunpla with some trusted seller. beside a safety reason, you can get a discount. Remember, money is the most important thing in this business. - Pick Your Scale
don't push yourself too hard . start with high grade . IMO , people got bored if you build something so hard. but if you resist to build that one, no problem. - Power of Searching
Try to compare about budgeting, model,scale, and anything. try to read some review too.
- Don't Break Your Relationship
Build gunpla doesn't make you being a psychopath. u can start a life normally and get a social life. don't get focus at the gunpla only and didnt care about your lovelife, family and social things.*don't forget to tell your lover : "Gunpla is cool dear, build with me :)" - Bootlegs vs Original
don't be confused because Bootlegs vs Original things .I never ever encourage you to bought a bootleg gunpla. it's your choice and you know the risk. But, if you support gunpla, buy a legal one too ^^ - Your Tools
Don't forget to buy modelling tools. a cheap one will be great for starter :)
*i'm sorry if there are some mistake and sometimes hurt people
