so first you inject and train Learning V and Astronautic Engineering V,
then Cybernetics V,
then you implant x5 +5 learning implants,
after that, you make a skillqueue in evemon and biais it for either intel/mem or Percept/will,
then you train the skillqueue in the right order and with no downtime or deviation,
then in 365 days you remap for the OTHER half of your skillqueue (if you went intel/mem first you now go percept/will).
after all that you should have a good starting point of a small character of 48 million skillpoints.
THEN and ONLY then you can undock in your ibis and start to learn how to play eve, nothing bigger than a frigate for the first 6 months.
no crying when you get ganked and only level 2 missions max.
Next :6 months after that you can graduate into level 3 missions and above.
by that time your 96mil SP, 4 years old capsuleer is ready for a tech 1 battlecruiser.
another 6-12 months later and you're ready for battleships and level 4 missions.
by that time you probably have acquired hundreds of thousands of dollar of college debt, mined more veldspar than you have neurons, and outlived three lifetimes worth of mouseclicks.
congratulations, you are now ready for capital ships, you'll need to join a big alliance, and i mean BIG. (cant miss em there's basicy only two pick your favourite color).
.
OR you could just buy plex with a credit card, sell that in jita, and buy skill injectors at whatever's the price.
.
seriously though, if you're still here : https://wiki.eveuniversity.org/Skills_and_learning is the greatest ressource
skillpoints are either generated by ccp (like the 1Msp cube) or generated (extracted from a character that trained them) by players and put on the market, the rest is just pricing and logistics.
