Accurizing a rifle

Hey everyone. I had a few questions about what you could do to make a rifle more accurate. the things i really know of are pillar bedding and glass bedding the stock ( im not sure what one is better). and there were a few other things. I really want to be able to do a lot of work at home because it would be enjoyable to me and i wont have to find a gunsmith because i live in NJ and you cant find any haha. So i was hopeing you could tell me what projects could be done to enhance my rifle preformace that i would be able to do myself and if some requires a little training i would like to know anyway bc i would like to be tought stuff. again i would like to do a lot on my own because it would be fun and feel good knowing i did the work on my rifle.... Thanks for your time!!
