How long should it take to master this song if I have been playing for 4 months?

It looks kinda hard, but i got the intro down already. Should I try something easier?
I really like this song and want to try it...

If you like Blues/Rock then add me as a friend. I need to talk to some Blues/Rock Musicians and need reccomendations.
hey im still refining Skynard songs i started learning over ayear ago. stick with the stuff YOU WANT TO PLAY. Skynard can be tough sometimes it helps me to rough in a verse. get something that sounds like the song then fill in the harder stuff as you get more comfortable. if you can play some of the more difficult songs youll be surprised how easy the simple stuff is. hope this helps. dont let the oak tree get in your way.
