1. Don't worry about getting as many plugins as you can, instead find one or two for each aspect of production and master them. Only move on once full mastery has been achieved.
2. The internet is your friend. For every question you may have, there will already be 54835483975 other people who would have had it already. In addition, there are incredibly helpful information out there. Whenever you don't feel like producing, read. No matter how much you think you know, there's always more.
3. Learn to move on. Sometimes you are trying to fix a sound, a song, and you spend so much time on fixing it that you lose track of where you want to go. Do not be afraid to delete things, or to start over. A blank page, although daunting, can be very inspiring.
