Programmer vs Inventor vs Trader

I like this 3 stuff, i like to code games, invent stuff and trade forex

but, in order to succeed in any of this 3 you can only choose 1, as they need 100% focus and concentration

of coz in the perfect world, if you can succeed in any of this 3 you will be billionaire

but in reality that is not the case

let start with inventor

Inventor
=======
Cons: -need high capital cost(unless you invent crap you need at least hundred thousand)
          -need a lot of time (take years and years)
         -very hard to create something out of this world (without budget you can only invent crap)
          -once product is out very hard to find investor or buyer
         -expensive intellectual property license fee or patent fee

Pro: billionaire

traders
========
Cons: -hardest skill to acquire (you might spend 30 years and cannot find a way to profit)
          -you might only end up with a bunch of trading log or trading history

Pro: billionaire

programmer
==========
Cons: have the most competitor (as everyone and their dog know how to code)

Pro: -with your skill you can apply for jobs
        -and even the worst games can make some money ( a few buck from here and there)
        -if you failed after 30 years, at least you got tons and tons of product on the shelf, i guess you can still make a few buck from here and there
- and of coz, if you can create something like minecraft you are billionaire

guess i have to choose programmer
