Im completely new to the forum, I brought a maybe 3 or 4 foot tall Picea Abies from Miter 10 today for $20

I relatively new to Bonsai, been into it for a while but Im starting to get more serious about it just learning from youtube videos ..
Anyways I have some questions would be great to get some advice

So I guess first would it be a good idea to try to bonsai this plant ?
What should I do now ? Should I prune it, repot it, and let it grow for a season ? ..
Any advice would be a great help, thanks !
Cheers K
