A good trademark is something that can uniquely distinguish you, your company or it’s goods and services from those of others. To do so a good trademark should be:

Non-descriptive – don’t try and describe your goods and services with your trademark. You can always accompany the trademark with a separate slogan or descriptive text to tell your customers what you do e.g. register “Mint” as your trademark for auto services not “Mint Auto Services”.
Suggestive – while not necessary, a good trademark may be suggestive or allude to the quality or other characteristic of the goods or services e.g. “SleepyHead” for beds and bedding.
