I don't have a bullet journal but I do like having planners and calendars that I can look at so I guess I'll probably have some semi-valid advice xD

1. Maybe make a time every day to write in it, if you have something new that's coming up or anything. You could listen to music or something during this time too if it's not really something you love to do

2. WASHI TAPE. Washi tape is amazing. Honestly I think half the point of planners is to decorate them hehe

I don't know why I made it a numbered list if there were only two things but uh...Hope that helps! :)

Cool! I just started my bullet journal about a month ago. These are some things that have helped me.

1. Find inspiration. Look up pictures or watch videos of other people's spreads and find stuff that you like. This makes me excited to plan in my journal and incorporate aesthetics and logs that I think will work for me. 

2. Don't limit yourself. The nice thing about a bullet journal is that it can be literally whatever you want it to be, so don't start off by telling yourself what you can and can't do. It's totally fine if you don't plan a week if you don't feel like it, insert spontaneous lists, or throw in a journal entry or a sketch here and there. Of course, it depends on what you want to use it for, but my point is don't force yourself to do what everyone else is doing if that isn't what you want to do.

3. Decorate it. This is mostly if you are going for a more artsy/aesthetic journal (which you don't have to do!), but it definitely motivates me to use it more if I spent time designing it. It also helps if you have some really pretty stationery you've been dying to use! 

4. Try different things. If you find that certain trackers, spreads, or layouts don't work for you, switch things up and find out what does work for you. 

5. Keep it on a desk or somewhere you see it every day. I use mine mostly for writing down events and to-do lists, so I like to keep it on my school desk. Of course, you don't have to use it every day if that doesn't work for you.

6. Keep it simple... kind of? I actually don't like when people say this. I think you should have it as simple or complicated as keeps you engaged and works with your schedule. You don't have to do just boxes if you'll die of boredom.

It mostly depends on what you want to use it for. I use mine as a creative brain dump, basically, so it consists of lists, to-dos, events, and the occasional watercolor painting. 

I hope this was a little bit helpful. I'm not great at explaining things. :/
