I will not be tempted during TV commercials to check for email. I will try and get out of the house at least once a week, if it is necessary or not. I will remember that my bank is not forgiving if I forget to pay the minimum credit card balance because I was too busy with my homepage. The passive voice is to be avoided. Prepositions are not words to end sentences with.
Comparisons are as bad as cliches too.
Contractions aren't necessary either. Be more or less specific. Don't be redundant - don't use more words than necessary because it's highly superfluous. Tell me what you know. Exaggeration is a billion times worse than understatement.
