Hi there,
I'd suggest you just start playing with a 3 or 4 gap till you reach a higher level, maybe like 52 or 64 and then open a 9gap to farm the sp you need. That way you wont be bored in the beginning. You can get there relatively fast while doing quests, but not too fast so you can earn abit of gold for a nice 7th or 8th degree farming-weapon.
Or if you have the money and the patience, you can get yourself powerfarmed at the ongs. Get yourself plvled till lvl 25

delvl till 20

repeat. Do this till you have all the sp you need. This is by far the fastest way.
But because you just started playing i would suggest you to go with the first option

Best way to learn the game
hope i helped
