Statistics and Indexes

When is it okay to let SQL Server to make a statistic for columns in your queries, and when should you take those statistics and make an index out of them? What I do is to test all of my procs, and if they generate system statistics (_WA_SYS%), then I add an index to the table for the column in the statistic. But is this a good practice?
