What to do with this 15 day old?

First thing you'll need to do is to get a better calendar. No way those are 15 days old. Takes a month or longer to get fan leaves that large.
If you only have space for the one plant, would top it once or twice, and train it to spread-out, instead of growing straight-up. (small bamboo stakes and twist-ties to train the branches)

Low stress training...
