Any music instrument requires dedication and practice, love for it will inspire this.
So if you can do it then maybe 2 to 3 years of intense - say 3 to 4 hours a day - practice should be great.
But it is "blood sweat and tears" till then.
If you have an aptitude then you may cut this a bit shorter.
Persevere, and when your fingers hurt and bleed, use oils and keep on practicing till that falls away and love will take you through.
