With only three posts and you want to teach other newbies. This is strange and makes me think that you are not newbie at all.
There's nothing wrong with sharing knowledge if op wants to. It's just feels unusual for a newcomer to offer motivational advice on the forum, but it's not a bad thing. While the person may be new, on the forum, they might have other knowledge outside. I've seen several posts in the past few days about motivating newbies, and I'm not sure where this idea is coming from. However, it's a positive thing. I want newbies to know that this forum is a free space to learn, as long as you follow the rules and don't break any. Just focus on gaining knowledge for now, and avoid being too confident in what little you know. As you acquire more knowledge, you'll see improvement and growth in your rank.
