Excellent, proven methods:

Mine coins by getting a job that pays fiat, then exchange that fiat for Bitcoins.  If you already have a job then simply find something you can do on the side that generates fiat and exchange that fiat for Bitcoin.

Alternatively, create something of value that people are willing to pay for using Bitcoins.

All time tested methods that will net you Bitcoin.  In effect, you are "mining" them.
