I'd say dive right in. A lot of people view ranked climbing as a goal to attain, a badge of honor to grind towards. I however view my rating as my current skill level. I don't cheese the system or abuse mechanics to win win win, I just play the way I always play and let my rank sort itself out. No benefit in artificially inflating my rating. Just play and you'll naturally climb/get better.
This ^ is a completely valid point of view as well. The real answer depends on what you want out of the game. I disagree with this poster because this method of play will not get me what I want out of the game. But there is nothing wrong with approaching ranked ques with this mindset.
I personally view ranked as a way to measure myself against everyone else when I'm at my best. So I play normals to break in/learn new champs that I want to eventually play in ranked, or when I'm feeling tired or just want to play something casually that's fun, but not great in the meta, like jungle Galio or something. I only play ranked games in my best roles with my best champs. I know I'll never make the LCS, and I'll probably never even make Diamond, but I like to only play ranked when I'm at my best and really try to push my ranking up each season, becoming a better player and trying to get into a higher percentile of the community each time.
I get a sense of accomplishment from finding out what works in the meta and finding strategies that improve my chances of winning in each patch. I think a lot of people who take ranked games "seriously" share this feeling. However, it is still a game, and unless you are one of the 700ish people out of 70 million who plans to make a living off of playing this game, your personal view of ranked games will also impact when you should start playing them.
My advice above will get you to a higher ranking than this poster's will, but that doesn't mean my view is right and his is wrong. It depends on what you personally want out of the game.
