If you make under ~$140k, you can put in $7000 this year and you have until April to put in another $6500 from last year's contribution limit too.
It's a good retirement investment. The earlier you put the money in the better: the best time put in the money is at the start of the year, but the 2nd best time is now. If you aren't sure what to invest in, either a balanced index fund or a targeted retirement fund is probably your best bet.
