Some good advice is looking around and conversating with people. I advise you to start spending more time on getting to know people and when you are well-known or have good reputation from the current staff, you are welcome to apply. I also want to say being professional is something you need to work on. I only hire mods that are Thick-skinned, well behaved, bring value, and are professional.
Some advice on keeping a good reputation from staff:
Don't Bug us about becoming moderator if you are not going to put in the work.
Get known around the site
Explore the features.
keep a good history.
Such things like calling yourself a "mod wannabe" would definitely be looked down upon by any well experienced Administrator, Global Mod, or application maintainer on any forum.
A good role model is someone who guides users to success and helps users when they need help most.
EDIT: I found this useful Reddit thread shared by @VGmoose which gives a ton of info about modding, click here for more information. Thanks Moose
