Being bored, or avoiding boredom, are two very important issues. Whereas someone may be excited about reading, yoga, sex, or whatever, avoidance of boredom is a complex issue. We have to find what turns us on and learn whether we have the motivation to pursue what turns us on. You can have ambition, but if you don't have the motivation to achieve your ambitions, you won't get far.
My best advice to avoid being bored? Get very bored and for quite some time; you'll quickly find out that being bored is no fun. That will motivate you to avoid being bored! You will do anything to avoid that status, including pursuing activities like having sex, meditation, yoga, going out, and so on.
I was bored this afternoon, so then I got to read this post and that got me motivated to write, and offer advice (which i love to do, even for free, even if unsolicited!). Now, I am not bored anymore. But I am finishing this post, so there's a chance I will get bored again. Please, someone, post a message on this forum that will motivate me to think and write about it, so I can avoid getting bored again!
