Nothing is good enough if you don't follow basic computer security stuff... like not downloading untrusted crap, not opening unknown email attachments, not being gullible with all the spam and scam that arrives in email these days, keeping your browser and OS up to date with the latest security updates, etc.... If you do follow those safe practices, then it should be enough...
A Plumber in Tampa, Florida earns an average wage of $20.00 per hour.
By the same token, though, demand for particular career paths (and the salaries that employers are willing to pay) may vary significantly depending upon where you live. In North Carolina, for instance, a plumber averages $57,996 a year. The same job, however, only earns $51,340 in New Jersey and $49,890 in Hawaii.
